) ?all av dd and av ss pins (regardless if adc module is not used) (see section 2.2 ?decoupling capacitors? ) ?v cap /v ddcore (see section 2.3 ?capacitor on internal voltage regulator (v cap /v ddcore )? ) ?mclr pin (see section 2.4 ?master clear (mclr) pin? ) ? pgecx/pgedx pins used for in-circuit serial programming? (icsp?) and debugging purposes (see section 2.5 ?icsp pins? ) ? osc1 and osc2 pins when external oscillator source is used (see section 2.6 ?external oscillator pins? ) 2.2 decoupling capacitors the use of decoupling capacitors on every pair of power supply pins, such as v dd , v ss , av dd , and av ss is required. consider the following criteria when using decoupling capacitors: ? value and type of capacitor: recommendation of 0.1 f (100 nf), 10-20v. this capacitor should be a low-esr and have resonance frequency in the range of 20 mhz and higher. it is recommended that ceramic capacitors be used. ? placement on the printed circuit board: the decoupling capacitors should be placed as close to the pins as possible. it is recommended to place the capacitors on the same side of the board as the device. if space is constricted, the capacitor can be placed on another layer on the pcb using a via; however, ensure that the trace length from the pin to the capacitor is within one-quarter inch (6 mm) in length. ? handling high frequency noise: if the board is experiencing high frequency noise, upward of tens of mhz, add a second ceramic-type capaci- tor in parallel to the above described decoupling capacitor. the value of the second capacitor can be in the range of 0.01 f to 0.001 f. place this second capacitor next to the primary decoupling capacitor. in high-speed circuit designs, consider implementing a decade pair of capacitances as close to the power and ground pins as possible. for example, 0.1 f in parallel with 0.001 f. ? maximizing performance: on the board layout from the power supply circuit, run the power and return traces to the decoupling capacitors first, and then to the device pins. this ensures that the decoupling capacitors are first in the power chain. equally important is to keep the trace length between the capacitor and the power pins to a minimum, thereby reducing pcb track inductance. note 1: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 family of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?dspic33f/pic24h family reference manual? . please see the microchip web site (www.microchip.com) for the latest dspic33f/pic24h family reference manual sections. 2: some registers and associated bits described in this section may not be avail- able on all devices. refer to section 4.0 ?memory organization? in this data sheet for device-specific register and bit information. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 26 preliminary ? 2009 microchip technology inc. figure 2-1: recommended minimum connection 2.2.1 tank capacitors on boards with power traces running longer than six inches in length, it is suggested to use a tank capacitor for integrated circuits including dscs to supply a local power source. the value of the tank capacitor should be determined based on the trace resistance that con- nects the power supply source to the device, and the maximum current drawn by the device in the applica- tion. in other words, select the tank capacitor so that it meets the acceptable voltage sag at the device. typical values range from 4.7 f to 47 f. 2.3 capacitor on internal voltage regulator (v cap /v ddcore ) a low-esr (< 5 ohms) capacitor is required on the v cap /v ddcore pin, which is used to stabilize the voltage regulator output voltage. the v cap /v ddcore pin must not be connected to v dd , and must have a capacitor between 4.7 f and 10 f, 16v connected to ground. the type can be ceramic or tantalum. refer to section 27.0 ?electrical characteristics? for additional information. the placement of this capacitor should be close to the v cap /v ddcore . it is recommended that the trace length not exceed one-quarter inch (6 mm). refer to section 24.2 ?on-chip voltage regulator? for details. 2.4 master clear (mclr ) pin the mclr pin provides for two specific device functions: ? device reset ? device programming and debugging. during device programming and debugging, the resistance and capacitance that can be added to the pin must be considered. device programmers and debuggers drive the mclr pin. consequently, specific voltage levels (v ih and v il ) and fast signal transitions must not be adversely affected. therefore, specific values of r and c will need to be adjusted based on the application and pcb requirements. for example, as shown in figure 2-2, it is recommended that the capacitor c, be isolated from the mclr pin during programming and debugging operations. place the components shown in figure 2-2 within one-quarter inch (6 mm) from the mclr pin. figure 2-2: example of mclr pin connections dspic33f v dd v ss v dd v ss v ss v dd av dd av ss v dd v ss 0.1 f ceramic 0.1 f ceramic 0.1 f ceramic 0.1 f ceramic c r v dd mclr 0.1 f ceramic v cap /v ddcore 10 ? r1 note 1: r ? 10 k ? is recommended. a suggested starting value is 10 k ? . ensure that the mclr pin v ih and v il specifications are met. 2: r1 ? 470 ? will limit any current flowing into mclr from the external capacitor c, in the event of mclr pin breakdown, due to electrostatic discharge (esd) or electrical overstress (eos). ensure that the mclr pin v ih and v il specifications are met. c r1 r v dd mclr dspic33f jp ?

(icsp?) and debugging pur- poses. it is recommended to keep the trace length between the icsp connector and the icsp pins on the device as short as possible. if the icsp connector is expected to experience an esd event, a series resistor is recommended, with the value in the range of a few tens of ohms, not to exceed 100 ohms. pull-up resistors, series diodes, and capacitors on the pgcx and pgdx pins are not recommended as they will interfere with the programmer/debugger communi- cations to the device. if such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. alternatively, refer to the ac/dc characteristics and timing requirements information in the respective device flash programming specification for information on capacitive loading limits and pin input voltage high (v ih ) and input low (v il ) requirements. ensure that the ?communication channel select? (i.e., pgecx/pgedx pins) programmed into the device matches the physical connections for the icsp to mplab ? icd 2, mplab ? icd 3, or mplab ? real ice?. for more information on icd 2, icd 3, and real ice connection requirements, refer to the following documents that are available on the microchip web site. ? ?mplab ? icd 2 in-circuit debugger user's guide? ds51331 ? ?using mplab ? icd 2?

(poster) ds51749 2.6 external oscillator pins many dscs have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator (refer to section 9.0 ?oscillator configuration? for details). the oscillator circuit should be placed on the same side of the board as the device. also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. the load capacitors should be placed next to the oscillator itself, on the same side of the board. use a grounded copper pour around the oscillator circuit to isolate them from surrounding circuits. the grounded copper pour should be routed directly to the mcu ground. do not run any signal traces or power traces inside the ground pour. also, if using a two-sided board, avoid any traces on the other side of the board where the crystal is placed. a suggested layout is shown in figure 2-3. figure 2-3: suggested placement of the oscillator circuit 13 main oscillator guard ring guard trace secondary oscillator 14 15 16 17 18 19 20 dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 28 preliminary ? 2009 microchip technology inc. 2.7 oscillator value conditions on device start-up if the pll of the target device is enabled and configured for the device start-up oscillator, the maximum oscillator source frequency must be limited to 4 mhz < f in < 8 mhz to comply with device pll start-up conditions. this means that if the external oscillator frequency is outside this range, the application must start-up in the frc mode first. the default pll settings after a por with an oscillator frequency outside this range will violate the device operating speed. once the device powers up, the application firmware can initialize the pll sfrs, clkdiv, and plldbf to a suitable value, and then perform a clock switch to the oscillator + pll clock source. note that clock switching must be enabled in the device configuration word. 2.8 configuration of analog and digital pins during icsp operations if mplab icd 2, icd 3, or real ice is selected as a debugger, it automatically initializes all of the a/d input pins (anx) as ?digital? pins, by setting all bits in the adpcfg and adpcfg2 registers. the bits in the registers that correspond to the a/d pins that are initialized by mplab icd 2, icd 3, or real ice, must not be cleared by the user application firmware; otherwise, communication errors will result between the debugger and the device. if your application needs to use certain a/d pins as analog input pins during the debug session, the user application must clear the corresponding bits in the adpcfg and adpcfg2 registers during initialization of the adc module. when mplab icd 2, icd 3, or real ice is used as a programmer, the user application firmware must correctly configure the adpcfg and adpcfg2 registers. automatic initialization of these registers is only done during debugger operation. failure to correctly configure the register(s) will result in all a/d pins being recognized as analog input pins, resulting in the port value being read as a logic ' 0 ', which may affect user application functionality. 2.9 unused i/os unused i/o pins should be configured as outputs and driven to a logic-low state. alternatively, connect a 1k to 10k resistor to v ss on unused pins and drive the output to logic low. 2.10 typical application connection examples examples of typical application connections are shown in figure 2-4 through figure 2-11. ?

16-bit mcu and dsc programmer?s ref- erence manual ? (ds70157) for information on the sr bits affected by each instruction. the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 cpu incorporates hardware support for both multiplication and division. this includes a dedicated hardware multiplier and support hardware for 16-bit-divisor division. 3.5.1 multiplier using the high-speed, 17-bit x 17-bit multiplier of the dsp engine, the alu supports unsigned, signed or mixed sign operation in several mcu multiplication modes: ? 16-bit x 16-bit signed ? 16-bit x 16-bit unsigned ? 16-bit signed x 5-bit (literal) unsigned ? 16-bit unsigned x 16-bit unsigned ? 16-bit unsigned x 5-bit (literal) unsigned ? 16-bit unsigned x 16-bit signed ? 8-bit unsigned x 8-bit unsigned 3.5.2 divider the divide block supports 32-bit/16-bit and 16-bit/16-bit signed and unsigned integer divide operations with the following data sizes: ? 32-bit signed/16-bit signed divide ? 32-bit unsigned/16-bit unsigned divide ? 16-bit signed/16-bit signed divide ? 16-bit unsigned/16-bit unsigned divide the quotient for all divide instructions ends up in w0 and the remainder in w1. 16-bit signed and unsigned div instructions can specify any w register for both the 16-bit divisor (wn) and any w register (aligned) pair (w(m + 1):wm) for the 32-bit dividend. the divide algorithm takes one cycle per bit of divisor, so both 32-bit/ 16-bit and 16-bit/16-bit instructions take the same number of cycles to execute. 3.6 dsp engine the dsp engine consists of a high-speed, 17-bit x 17-bit multiplier, a barrel shifter and a 40-bit adder/ subtracter (with two target accumulators, round and saturation logic). the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 is a single-cycle instruction flow architecture; therefore, concurrent opera- tion of the dsp engine with mcu instruction flow is not possible. however, some mcu alu and dsp engine resources can be used concurrently by the same instruc- tion (for example, ed, edac). the dsp engine can also perform inherent accumulator-to-accumulator operations that require no additional data. these instructions are add, sub and neg . the dsp engine has options selected through bits in the cpu core control register (corcon), as listed below: ? fractional or integer dsp multiply (if) ? signed or unsigned dsp multiply (us) ? conventional or convergent rounding (rnd) ? automatic saturation on/off for acca (sata) ? automatic saturation on/off for accb (satb) ? automatic saturation on/off for writes to data memory (satdw) ? accumulator saturation mode selection (accsat) a block diagram of the dsp engine is shown in figure 3-3. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 42 preliminary ?

1. ? for a 16-bit integer, the data range is -32768 (0x8000) to 32767 (0x7fff) including 0. ? for a 32-bit integer, the data range is -2,147,483,648 (0x8000 0000) to 2,147,483,647 (0x7fff ffff). when the multiplier is configured for fractional multiplication, the data is represented as a 2?s complement fraction, where the msb is defined as a sign bit and the radix point is implied to lie just after the sign bit (qx format). the range of an n-bit 2?s complement fraction with this implied radix point is -1.0 to (1 ? 2 1-n ). for a 16-bit fraction, the q15 data range is -1.0 (0x8000) to 0.999969482 (0x7fff) including 0 and has a precision of 3.01518x10 -5 . in fractional mode, the 16 x 16 multiply operation generates a 1.31 product that has a precision of 4.65661 x 10 -10 . the same multiplier is used to support the mcu multiply instructions, which include integer 16-bit signed, unsigned and mixed sign multiply operations. the mul instruction can be directed to use byte or word-sized operands. byte operands will direct a 16-bit result, and word operands will direct a 32-bit result to the specified register(s) in the w array. 3.6.2 data accumulators and adder/subtracter the data accumulator consists of a 40-bit adder/ subtracter with automatic sign extension logic. it can select one of two accumulators (a or b) as its pre- accumulation source and post-accumulation destination. for the add and lac instructions, the data to be accumulated or loaded can be optionally scaled using the barrel shifter prior to accumulation. 3.6.2.1 adder/subtracter, overflow and saturation the adder/subtracter is a 40-bit adder with an optional zero input into one side, and either true or complement data into the other input. ? in the case of addition, the carry/b orrow input is active-high and the other input is true data (not complemented). ? in the case of subtraction, the carry/borrow input is active-low and the other input is complemented. the adder/subtracter generates overflow status bits, sa/sb and oa/ob, which are latched and reflected in the status register: ? overflow from bit 39: this is a catastrophic overflow in which the sign of the accumulator is destroyed. ? overflow into guard bits, 32 through 39: this is a recoverable overflow. this bit is set whenever all the guard bits are not identical to each other. the adder has an additional saturation block that controls accumulator data saturation, if selected. it uses the result of the adder, the overflow status bits described previously and the sat dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 44 preliminary ? 2009 microchip technology inc. the sa and sb bits are modified each time data passes through the adder/subtracter, but can only be cleared by the user application. when set, they indicate that the accumulator has overflowed its maximum range (bit 31 for 32-bit saturation or bit 39 for 40-bit saturation) and will be saturated (if saturation is enabled). when saturation is not enabled, sa and sb default to bit 39 overflow and thus, indicate that a cata- strophic overflow has occurred. if the covte bit in the intcon1 register is set, sa and sb bits will generate an arithmetic warning trap when saturation is disabled. the overflow and saturation status bits can optionally be viewed in the status register (sr) as the logical or of oa and ob (in bit oab) and the logical or of sa and sb (in bit sab). programmers can check one bit in the status register to determine if either accumulator has overflowed, or one bit to determine if either accumulator has saturated. this is useful for complex number arithmetic, which typically uses both accumulators. the device supports three saturation and overflow modes: ? bit 39 overflow and saturation: when bit 39 overflow and saturation occurs, the saturation logic loads the maximally positive 9.31 (0x7fffffffff) or maximally negative 9.31 value (0x8000000000) into the target accumu- lator. the sa or sb bit is set and remains set until cleared by the user application. this condition is referred to as ?super saturation? and provides protection against erroneous data or unexpected algorithm problems (such as gain calculations). ? bit 31 overflow and saturation: when bit 31 overflow and saturation occurs, the saturation logic then loads the maximally positive 1.31 value (0x007fffffff) or maximally nega- tive 1.31 value (0x0080000000) into the target accumulator. the sa or sb bit is set and remains set until cleared by the user application. when this saturation mode is in effect, the guard bits are not used, so the oa, ob or oab bits are never set. ? bit 39 catastrophic overflow: the bit 39 overflow status bit from the adder is used to set the sa or sb bit, which remains set until cleared by the user application. no saturation operation is performed, and the accumulator is allowed to overflow, destroying its sign. if the covte bit in the intcon1 register is set, a catastrophic overflow can initiate a trap exception. 3.6.3 accumulator ?write back? the mac class of instructions (with the exception of mpy, mpy.n, ed and edac ) can optionally write a rounded version of the high word (bits 31 through 16) of the accumulator that is not targeted by the instruction into data space memory. the write is performed across the x bus into combined x and y address space. the following addressing modes are supported: ? w13, register direct: the rounded contents of the non-target accumulator are written into w13 as a 1.15 fraction. ? [w13] + = 2, register indirect with post-increment: the rounded contents of the non-target accumulator are written into the address pointed to by w13 as a 1.15 fraction. w13 is then incremented by 2 (for a word write). 3.6.3.1 round logic the round logic is a combinational block that performs a conventional (biased) or convergent (unbiased) round function during an accumulator write (store). the round mode is determined by the state of the rnd bit in the corcon register. it generates a 16-bit, 1.15 data value that is passed to the data space write saturation logic. if rounding is not indicated by the instruction, a truncated 1.15 data value is stored and the least significant word is simply discarded. conventional rounding zero-extends bit 15 of the accu- mulator and adds it to the accxh word (bits 16 through 31 of the accumulator). ? if the accxl word (bits 0 through 15 of the accumulator) is between 0x8000 and 0xffff (0x8000 included), accxh is incremented. ? if accxl is between 0x0000 and 0x7fff, accxh is left unchanged. a consequence of this algorithm is that over a succession of random rounding operations, the value tends to be biased slightly positive. convergent (or unbiased) rounding operates in the same manner as conventional rounding, except when accxl equals 0x8000. in this case, the least significant bit (bit 16 of the accumulator) of accxh is examined: ? if it is ? 1 ?, accxh is incremented. ? if it is ? 0 ?, accxh is not modified. assuming that bit 16 is effectively random in nature, this scheme removes any rounding bias that may accumulate. the sac and sac.r instructions store either a truncated ( sac ), or rounded ( sac.r ) version of the contents of the target accumulator to data memory via the x bus, subject to data saturation (see section 3.6.3.2 ?data space write saturation? ). for the mac class of instructions, the accumulator write- back operation functions in the same manner, addressing combined mcu (x and y) data space though the x bus. for this class of instructions, the data is always subject to rounding. ?

for input data greater than 0x007fff, data written to memory is forced to the maximum positive 1.15 value, 0x7fff. ? for input data less than 0xff8000, data written to memory is forced to the maximum negative 1.15 value, 0x8000. the most significant bit of the source (bit 39) is used to determine the sign of the operand being tested. if the satdw bit in the corcon register is not set, the input data is always passed through unmodified under all conditions. 3.6.4 barrel shifter the barrel shifter can perform up to 16-bit arithmetic or logic right shifts, or up to 16-bit left shifts in a single cycle. the source can be either of the two dsp accumulators or the x bus (to support multi-bit shifts of register or memory data). the shifter requires a signed binary value to determine both the magnitude (number of bits) and direction of the shift operation. a positive value shifts the operand right. a negative value shifts the operand left. a value of ? 0 ? does not modify the operand. the barrel shifter is 40 bits wide, thereby obtaining a 40-bit result for dsp shift operations and a 16-bit result for mcu shift operations. data from the x bus is presented to the barrel shifter between bit positions 16 and 31 for right shifts, and between bit positions 0 and 16 for left shifts. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 46 preliminary ?

. user application access to the program memory space is restricted to the lower half of the address range (0x000000 to 0x7fffff). the exception is the use of tblrd/tblwt operations, which use tblpag<7> to permit access to the configuration bits and device id sections of the configuration memory space. the memory maps for the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices are shown in figure 4-1. figure 4-1: program memory maps for dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices note: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the dspic33f/pic24h family reference manual , ?section 4. program memory?

2009 microchip technology inc. 4.1.1 program memory organization the program memory space is organized in word-addressable blocks. although it is treated as 24 bits wide, it is more appropriate to think of each address of the program memory as a lower and upper word, with the upper byte of the upper word being unimplemented. the lower word always has an even address, while the upper word has an odd address (see figure 4-2). program memory addresses are always word-aligned on the lower word, and addresses are incremented or decremented by two during the code execution. this arrangement provides compatibility with data memory space addressing and makes data in the program memory space accessible. 4.1.2 interrupt and trap vectors all dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices reserve the addresses between 0x00000 and 0x000200 for hard-coded program execution vectors. a hardware reset vector is provided to redirect code execution from the default value of the pc on device reset to the actual start of code. a goto instruction is programmed by the user application at 0x000000, with the actual address for the start of code at 0x000002. the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices also have two interrupt vector tables, located from 0x000004 to 0x0000ff and 0x000100 to 0x0001ff. these vector tables allow each of the device interrupt sources to be handled by separate interrupt service routines (isrs). a more detailed discussion of the interrupt vector tables is provided in section 7.1 ?interrupt vector table?

). the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices implement up to 9 kbytes of data memory. should an ea point to a location outside of this area, an all-zero word or byte will be returned. 4.2.1 data space width the data memory space is organized in byte addressable, 16-bit wide blocks. data is aligned in data memory and registers as 16-bit words, but all data space eas resolve to bytes. the least significant bytes (lsbs) of each word have even addresses, while the most significant bytes (msbs) have odd addresses. 4.2.2 data memory organization and alignment to maintain backward compatibility with pic ? mcu devices and improve data space memory usage efficiency, the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 instruction set sup- ports both word and byte operations. as a conse- quence of byte accessibility, all effective address calculations are internally scaled to step through word-aligned memory. for example, the core recog- nizes that post-modified register indirect addressing mode [ws++] that results in a value of ws + 1 for byte operations and ws + 2 for word operations. data byte reads will read the complete word that contains the byte, using the lsb of any ea to determine which byte to select. the selected byte is placed onto the lsb of the data path. that is, data memory and registers are organized as two parallel byte-wide entities with shared (word) address decode but separate write lines. data byte writes only write to the corresponding side of the array or register that matches the byte address. all word accesses must be aligned to an even address. misaligned word data fetches are not supported, so care must be taken when mixing byte and word operations, or translating from 8-bit mcu code. if a misaligned read or write is attempted, an address error trap is generated. if the error occurred on a read, the instruction underway is completed. if the error occurred on a write, the instruction is executed but the write does not occur. in either case, a trap is then executed, allowing the system and/or user application to examine the machine state prior to execution of the address fault. all byte loads into any w register are loaded into the least significant byte. the most significant byte is not modified. a sign-extend instruction ( se ) is provided to allow user applications to translate 8-bit signed data to 16-bit signed values. alternatively, for 16-bit unsigned data, user applications can clear the msb of any w register by executing a zero-extend ( ze ) instruction on the appropriate address. 4.2.3 sfr space the first 2 kbytes of the near data space, from 0x0000 to 0x07ff, is primarily occupied by special function registers (sfrs). these are used by the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 core and peripheral modules for controlling the operation of the device. sfrs are distributed among the modules that they control, and are generally grouped together by module. much of the sfr space contains unused addresses; these are read as ? 0 ?. 4.2.4 near data space the 8 kbyte area between 0x0000 and 0x1fff is referred to as the near data space. locations in this space are directly addressable via a 13-bit absolute address field within all memory direct instructions. additionally, the whole data space is addressable using mov instructions, which support memory direct addressing mode with a 16-bit address field, or by using indirect addressing mode using a working register as an address pointer. note: the actual set of peripheral features and interrupts varies by the device. refer to the corresponding device tables and pinout diagrams for device-specific information. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 50 preliminary ?

2009 microchip technology inc. 4.2.7 software stack in addition to its use as a working register, the w15 register in the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices is also used as a software stack pointer. the stack pointer always points to the first available free word and grows from lower to higher addresses. it predecrements for stack pops and post-increments for stack pushes, as shown in figure 4-6. for a pc push during any call instruc- tion, the msb of the pc is zero-extended before the push, ensuring that the msb is always clear. the stack pointer limit register (splim) associated with the stack pointer sets an upper address boundary for the stack. splim is uninitialized at reset. as is the case for the stack pointer, splim<0> is forced to ? 0 ? because all stack operations must be word-aligned. whenever an ea is generated using w15 as a source or destination pointer, the resulting address is compared with the value in splim. if the contents of the stack pointer (w15) and the splim register are equal and a push operation is performed, a stack error trap will not occur. the stack error trap will occur on a subsequent push operation. for example, to cause a stack error trap when the stack grows beyond address 0x1800 in ram, initialize the splim with the value 0x17fe. similarly, a stack pointer underflow (stack error) trap is generated when the stack pointer address is found to be less than 0x0800. this prevents the stack from interfering with the special function register (sfr) space. a write to the splim register should not be immediately followed by an indirect read operation using w15. figure 4-6: call stack frame 4.3 instruction addressing modes the addressing modes shown in table 4-65 form the basis of the addressing modes optimized to support the specific features of individual instructions. the addressing modes provided in the mac class of instructions differ from those in the other instruction types. 4.3.1 file register instructions most file register instructions use a 13-bit address field (f) to directly address data present in the first 8192 bytes of data memory (near data space). most file register instructions employ a working register, w0, which is denoted as wreg in these instructions. the destination is typically either the same file register or wreg (with the exception of the mul instruction), which writes the result to a register or register pair. the mov instruction allows additional flexibility and can access the entire data space. 4.3.2 mcu instructions the three-operand mcu instructions are of the form: operand 3 = operand 1 ?

register direct ? register indirect ? register indirect post-modified ? register indirect pre-modified ? register indirect with register offset (indexed) ? register indirect with literal offset ? 8-bit literal ? 16-bit literal 4.3.4 mac instructions the dual source operand dsp instructions ( clr , ed , edac , mac , mpy , mpy.n , movsac and msc ), also referred to as mac instructions, use a simplified set of addressing modes to allow the user application to effectively manipulate the data pointers through register indirect tables. the two-source operand prefetch registers must be members of the set {w8, w9, w10, w11}. for data reads, w8 and w9 are always directed to the x ragu, and w10 and w11 are always directed to the y agu. the effective addresses generated (before and after modification) must, therefore, be valid addresses within x data space for w8 and w9 and y data space for w10 and w11. in summary, the following addressing modes are supported by the mac class of instructions: ? register indirect ? register indirect post-modified by 2 ? register indirect post-modified by 4 ? register indirect post-modified by 6 ? register indirect with register offset (indexed) 4.3.5 other instructions besides the addressing modes outlined previously, some instructions use literal constants of various sizes. for example, bra (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the disi instruction uses a 14-bit unsigned literal field. in some instructions, such as add acc , the source of an operand or result is implied by the opcode itself. certain operations, such as nop , do not have any operands. addressing mode description file register direct the address of the file register is specified explicitly. register direct the contents of a register are accessed directly. register indirect the contents of wn forms the effective address (ea). register indirect post-modified the contents of wn forms the ea. wn is post-modified (incremented or decremented) by a constant value. register indirect pre-modified wn is pre-modified (incremented or decremented) by a signed constant value to form the ea. register indirect with register offset (register indexed) the sum of wn and wb forms the ea. register indirect with literal offset the sum of wn and a literal forms the ea. note: for the mov instructions, the addressing mode specified in the instruction can differ for the source and destination ea. however, the 4-bit wb (register offset) field is shared by both source and destination (but typically only used by one). note: not all instructions support all the addressing modes given above. individual instructions may support different subsets of these addressing modes. note: register indirect with register offset addressing mode is available only for w9 (in x space) and w11 (in y space). dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 102 preliminary ? 2009 microchip technology inc. 4.4 modulo addressing modulo addressing mode is a method used to provide an automated means to support circular data buffers using hardware. the objective is to remove the need for software to perform data address boundary checks when executing tightly looped code, as is typical in many dsp algorithms. modulo addressing can operate in either data or program space (since the data pointer mechanism is essentially the same for both). one circular buffer can be supported in each of the x (which also provides the pointers into program space) and y data spaces. modulo addressing can operate on any w register pointer. however, it is not advisable to use w14 or w15 for modulo addressing since these two registers are used as the stack frame pointer and stack pointer, respectively. in general, any particular circular buffer can be configured to operate in only one direction as there are certain restrictions on the buffer start address (for incrementing buffers), or end address (for decrementing buffers), based upon the direction of the buffer. the only exception to the usage restrictions is for buffers that have a power-of-two length. as these buffers satisfy the start and end address criteria, they can operate in a bidirectional mode (that is, address boundary checks are performed on both the lower and upper address boundaries). 4.4.1 start and end address the modulo addressing scheme requires that a starting and ending address be specified and loaded into the 16-bit modulo buffer address registers: xmodsrt, xmodend, ymodsrt and ymodend (see table 4-1). the length of a circular buffer is not directly specified. it is determined by the difference between the corresponding start and end addresses. the maximum possible length of the circular buffer is 32k words (64 kbytes). 4.4.2 w address register selection the modulo and bit-reversed addressing control register, modcon<15:0>, contains enable flags as well as a w register field to specify the w address registers. the xwm and ywm fields select the registers that will operate with modulo addressing: ? if xwm = 15 , x ragu and x wagu modulo addressing is disabled. ? if ywm = 15 , y agu modulo addressing is disabled. the x address space pointer w register (xwm), to which modulo addressing is to be applied, is stored in modcon<3:0> (see table 4-1). modulo addressing is enabled for x data space when xwm is set to any value other than ?15? and the xmoden bit is set at modcon<15>. the y address space pointer w register (ywm) to which modulo addressing is to be applied is stored in modcon<7:4>. modulo addressing is enabled for y data space when ywm is set to any value other than ? 15 ? and the ymoden bit is set at modcon<14>. figure 4-7: modulo address ing operation example note: y space modulo addressing ea calculations assume word-sized data (lsb of every ea is always clear). 0x1100 0x1163 start addr = 0x1100 end addr = 0x1163 length = 0x0032 words byte address mov #0x1100, w0 mov w0, xmodsrt ;set modulo start address mov #0x1163, w0 mov w0, modend ;set modulo end address mov #0x8001, w0 mov w0, modcon ;enable w1, x agu for modulo mov #0x0000, w0 ;w0 holds buffer fill value mov #0x1110, w1 ;point w1 to buffer do again, #0x31 ;fill the 50 buffer locations mov w0, [w1++] ;fill the next location again: inc w0, w0 ;increment the fill value ?

the upper boundary addresses for incrementing buffers ? the lower boundary addresses for decrementing buffers it is important to realize that the address boundaries check for addresses less than or greater than the upper (for incrementing buffers) and lower (for decrementing buffers) boundary addresses (not just equal to). address changes can, therefore, jump beyond boundaries and still be adjusted correctly. 4.5 bit-reversed addressing bit-reversed addressing mode is intended to simplify data re-ordering for radix-2 fft algorithms. it is supported by the x agu for data writes only. the modifier, which can be a constant value or register contents, is regarded as having its bit order reversed. the address source and destination are kept in normal order. thus, the only operand requiring reversal is the modifier. 4.5.1 bit-reversed addressing implementation bit-reversed addressing mode is enabled in any of these situations: ? bwm bits (w register selection) in the modcon register are any value other than ? 15 ? (the stack cannot be accessed using bit-reversed addressing) ? the bren bit is set in the xbrev register ? the addressing mode used is register indirect with pre-increment or post-increment if the length of a bit-reversed buffer is m = 2 n bytes, the last ?n? bits of the data buffer start address must be zeros. xb<14:0> is the bit-reversed address modifier, or ?pivot point,? which is typically a constant. in the case of an fft computation, its value is equal to half of the fft data buffer size. when enabled, bit-reversed addressing is executed only for register indirect with pre-increment or post-increment addressing and word-sized data writes. it will not function for any other addressing mode or for byte-sized data, and normal addresses are generated instead. when bit-reversed addressing is active, the w address pointer is always added to the address modifier (xb), and the offset associated with the register indirect addressing mode is ignored. in addition, as word-sized data is a requirement, the lsb of the ea is ignored (and always clear). if bit-reversed addressing has already been enabled by setting the bren (xbrev<15>) bit, a write to the xbrev register should not be immediately followed by an indirect read operation using the w register that has been designated as the bit-reversed pointer. note: the modulo corrected effective address is written back to the register only when pre-modify or post-modify addressing mode is used to compute the effective address. when an address offset (such as [w7 + w2]) is used, modulo address correction is performed but the contents of the register remain unchanged. note: all bit-reversed ea calculations assume word-sized data (lsb of every ea is always clear). the xb value is scaled accordingly to generate compatible (byte) addresses. note: modulo addressing and bit-reversed addressing should not be enabled together. if an application attempts to do so, bit-reversed addressing will assume priority when active for the x wagu and x wagu, modulo addressing will be dis- abled. however, modulo addressing will continue to function in the x ragu. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 104 preliminary ?

using table instructions to access individual bytes or words anywhere in the program space ? remapping a portion of the program space into the data space (program space visibility) table instructions allow an application to read or write to small areas of the program memory. this capability makes the method ideal for accessing data tables that need to be updated periodically. it also allows access to all bytes of the program word. the remapping method allows an application to access a large block of data on a read-only basis, which is ideal for look-ups from a large table of static data. the application can only access the least significant word of the program word. 4.6.1 addressing program space since the address ranges for the data and program spaces are 16 and 24 bits, respectively, a method is needed to create a 23-bit or 24-bit program address from 16-bit data registers. the solution depends on the interface method to be used. for table operations, the 8-bit table page register (tblpag) is used to define a 32k word region within the program space. this is concatenated with a 16-bit ea to arrive at a full 24-bit program space address. in this format, the most significant bit of tblpag is used to determine if the operation occurs in the user memory (tblpag<7> = 0 ) or the configuration memory (tblpag<7> = 1 ). for remapping operations, the 8-bit program space visibility register (psvpag) is used to define a 16k word page in the program space. when the most significant bit of the ea is ? 1 ?, psvpag is concatenated with the lower 15 bits of the ea to form a 23-bit program space address. unlike table operations, this limits remapping operations strictly to the user memory area. table 4-67 and figure 4-9 show how the program ea is created for table operations and remapping accesses from the data ea. here, p<23:0> refers to a program space word, and d<15:0> refers to a data space word. table 4-67: program space address construction access type access space program space address <23> <22:16> <15> <14:1> <0> instruction access (code execution) user 0 pc<22:1> 0 0xx xxxx xxxx xxxx xxxx xxx0 tblrd/tblwt (byte/word read/write) user tblpag<7:0> data ea<15:0> 0xxx xxxx xxxx xxxx xxxx xxxx configuration tblpag<7:0> data ea<15:0> 1xxx xxxx xxxx xxxx xxxx xxxx program space visibility (block remap/read) user 0 psvpag<7:0> data ea<14:0> (1) 0 xxxx xxxx xxx xxxx xxxx xxxx note 1: data ea<15> is always ?

tblrdl (table read low): - in word mode, this instruction maps the lower word of the program space location (p<15:0>) to a data address (d<15:0>). - in byte mode, either the upper or lower byte of the lower program word is mapped to the lower byte of a data address. the upper byte is selected when byte select is ? 1 ?; the lower byte is selected when it is ? 0 ?. ? tblrdh ( table read high): - in word mode, this instruction maps the entire upper word of a program address (p<23:16>) to a data address. note that d<15:8>, the ?phantom byte?, will always be ? 0 ?. - in byte mode, this instruction maps the upper or lower byte of the program word to d<7:0> of the data address, in the tblrdl instruction. the data is always ? 0 ? when the upper ?phantom? byte is selected (byte select = 1 ). similarly, two table instructions, tblwth and tblwtl , are used to write individual bytes or words to a program space address. the details of their operation are explained in section 5.0 ?flash program memory? . for all table operations, the area of program memory space to be accessed is determined by the table page register (tblpag). tblpag covers the entire program memory space of the device, including user and configuration spaces. when tblpag<7> = 0 , the table page is located in the user memory space. when tblpag<7> = 1 , the page is located in configuration space. figure 4-10: accessing program memory with table instructions 0 8 16 23 00000000 00000000 00000000 00000000 ?phantom?

2009 microchip technology inc. 4.6.3 reading data from program memory using program space visibility the upper 32 kbytes of data space may optionally be mapped into any 16k word page of the program space. this option provides transparent access to stored constant data from the data space without the need to use special instructions (such as tblrdl/h ). program space access through the data space occurs if the most significant bit of the data space ea is ? 1 ? and program space visibility is enabled by setting the psv bit in the core control register (corcon<2>). the location of the program memory space to be mapped into the data space is determined by the program space visibility page register (psvpag). this 8-bit register defines any one of 256 possible pages of 16k words in program space. in effect, psvpag functions as the upper 8 bits of the program memory address, with the 15 bits of the ea functioning as the lower bits. by incrementing the pc by 2 for each program memory word, the lower 15 bits of data space addresses directly map to the lower 15 bits in the corresponding program space addresses. data reads to this area add a cycle to the instruction being executed, since two program memory fetches are required. although each data space address 8000h and higher maps directly into a corresponding program memory address (see figure 4-11), only the lower 16 bits of the 24-bit program word are used to contain the data. the upper 8 bits of any program space location used as data should be programmed with ? 1111 1111 ? or ? 0000 0000 ? to force a nop . this prevents possible issues should the area of code ever be accidentally executed. for operations that use psv and are executed outside a repeat loop, the mov and mov.d instructions require one instruction cycle in addition to the specified execution time. all other instructions require two instruction cycles in addition to the specified execution time. for operations that use psv, and are executed inside a repeat loop, these instances require two instruction cycles in addition to the specified execution time of the instruction: ? execution in the first iteration ? execution in the last iteration ? execution prior to exiting the loop due to an interrupt ? execution upon re-entering the loop after an interrupt is serviced any other iteration of the repeat loop will allow the instruction using psv to access data, to execute in a single cycle. figure 4-11: program space visibility operation note: psv access is temporarily disabled during table reads/writes. 23 15 0 psvpag data space program space 0x0000 0x8000 0xffff 02 0x000000 0x800000 0x010000 0x018000 when corcon<2> = 1 and ea<15> = 1 : the data in the page designated by psvpag is mapped into the upper half of the data memory space... data ea<14:0> ...while the lower 15 bits of the ea specify an exact address within the psv area. this corresponds exactly to the same lower 15 bits of the actual program space address. psv area ?

in-circuit serial programming? (icsp?) programming capability ? run-time self-programming (rtsp) icsp allows a dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 device to be serially programmed while in the end application circuit. this is done with two lines for programming clock and programming data (one of the alternate programming pin pairs: pgc1/pgd1, pgc2/pgd2 or pgc3/pgd3), and three other lines for power (v dd ), ground (v ss ) and master clear (mclr ). this allows customers to manu- facture boards with unprogrammed devices and then program the digital signal controller just before shipping the product. this also allows the most recent firmware or a custom firmware to be programmed. rtsp is accomplished using tblrd (table read) and tblwt (table write) instructions. with rtsp, the user application can write program memory data, either in blocks or ?rows? of 64 instructions (192 bytes) at a time, or a single program memory word, and erase program memory in blocks or ?pages? of 512 instructions (1536 bytes) at a time. 5.1 table instructions and flash programming regardless of the method used, all programming of flash memory is done with the table read and table write instructions. these allow direct read and write access to the program memory space from the data memory while the device is in normal operating mode. the 24-bit target address in the program memory is formed using bits<7:0> of the tblpag register and the effective address (ea) from a w register specified in the table instruction, as shown in figure 5-1. the tblrdl and the tblwtl instructions are used to read or write to bits<15:0> of program memory. tblrdl and tblwtl can access program memory in both word and byte modes. the tblrdh and tblwth instructions are used to read or write to bits<23:16> of program memory. tblrdh and tblwth can also access program memory in word or byte mode. figure 5-1: addressing for table registers note 1: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 5. ?flash pro- gramming?

0010 ? to configure for block erase. set the erase (nvmcon<6>) and wren (nvmcon<14>) bits. b) write the starting address of the page to be erased into the tblpag and w registers. c) write 0x55 to nvmkey. d) write 0xaa to nvmkey. e) set the wr bit (nvmcon<15>). the erase cycle begins and the cpu stalls for the duration of the erase cycle. when the erase is done, the wr bit is cleared automatically. 4. write the first 64 instructions from data ram into the program memory buffers (see example 5-2). 5. write the program block to flash memory: a) set the nvmop bits to ? 0001 ? to configure for row programming. clear the erase bit and set the wren bit. b) write 0x55 to nvmkey. c) write 0xaa to nvmkey. d) set the wr bit. the programming cycle begins and the cpu stalls for the duration of the write cycle. when the write to flash memory is done, the wr bit is cleared automatically. 6. repeat steps 4 and 5, using the next available 64 instructions from the block in data ram by incrementing the value in tblpag, until all 512 instructions are written back to flash memory. for protection against accidental operations, the write initiate sequence for nvmkey must be used to allow any erase or program operation to proceed. after the programming command has been executed, the user application must wait for the programming time until programming is complete. the two instructions following the start of the programming sequence should be nop s, as shown in example 5-3. example 5-1: erasing a program memory page ; set up nvmcon for block erase operation mov #0x4042, w0 ; mov w0, nvmcon ; initialize nvmcon ; init pointer to row to be erased mov #tblpage(prog_addr), w0 ; mov w0, tblpag ; initialize pm page boundary sfr mov #tbloffset(prog_addr), w0 ; initialize in-page ea[15:0] pointer tblwtl w0, [w0] ; set base address of erase block disi #5 ; block all interrupts with priority <7 ; for next 5 instructions mov #0x55, w0 mov w0, nvmkey ; write the 55 key mov #0xaa, w1 ; mov w1, nvmkey ; write the aa key bset nvmcon, #wr ; start the erase sequence nop ; insert two nops after the erase nop ; command is asserted dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 114 preliminary ?

cold reset ?warm reset a cold reset is the result of a power-on reset (por) or a brown-out reset (bor). on a cold reset, the fnosc configuration bits in the fosc configuration register select the device clock source. a warm reset is the result of all the other reset sources, including the reset instruction. on warm reset, the device will continue to operate from the current clock source as indicated by the current oscillator selection (cosc<2:0>) bits in the oscillator control (osccon<14:12>) register. the device is kept in a reset state until the system power supplies have stabilized at appropriate levels and the oscillator clock is ready. the sequence in which this occurs is detailed below and is shown in figure 6-2. 1. por reset: a por circuit holds the device in reset when the power supply is turned on. the por circuit is active until v dd crosses the v por threshold and the delay, t por , has elapsed. 2. bor reset: the on-chip voltage regulator has a bor circuit that keeps the device in reset until v dd crosses the v bor threshold and the delay, t bor , has elapsed. the delay, t bor , ensures that the voltage regulator output becomes stable. 3. pwrt timer: the programmable power-up timer continues to hold the processor in reset for a specific period of time (t pwrt ) after a bor. the delay t pwrt ensures that the system power supplies have stabilized at the appropriate level for full-speed operation. after the delay, t pwrt , has elapsed, the sysrst becomes inactive, which in turn enables the selected oscillator to start generating clock cycles. 4. oscillator delay: the total delay for the clock to be ready for various clock source selections is given in table 6-1. refer to section 9.0 ?oscillator configuration? for more information. 5. when the oscillator clock is ready, the processor begins execution from location 0x000000. the user application programs a goto instruction at the reset address, which redirects program execution to the appropriate start-up routine. 6. the fail-safe clock monitor (fscm), if enabled, begins to monitor the system clock when the system clock is ready and the delay, t fscm , elapsed. table 6-1: oscillator delay oscillator mode oscillator start-up delay oscillator start-up timer pll lock time total delay frc, frcdiv16, frcdivn t oscd (1) ??t oscd (1) frcpll t oscd (1) ?t lock (3) t oscd + t lock (1,3) xt t oscd (1) t ost (2) ?t oscd + t ost (1,2) hs t oscd (1) t ost (2) ?t oscd + t ost (1,2) ec ????

for details. the por status (por) bit in the reset control (rcon<0>) register is set to indicate the power-on reset. 6.3 brown-out reset (bor) and power-up timer (pwrt) the on-chip regulator has a brown-out reset (bor) circuit that resets the device when the v dd is too low (v dd < v bor ) for proper device operation. the bor circuit keeps the device in reset until v dd crosses the v bor threshold and the delay, t bor , has elapsed. the delay, t bor , ensures the voltage regulator output becomes stable. the bor status (bor) bit in the reset control (rcon<1>) register is set to indicate the brown-out reset. the device will not run at full speed after a bor as the v dd should rise to acceptable levels for full-speed operation. the pwrt provides power-up time delay (t pwrt ) to ensure that the system power supplies have stabilized at the appropriate levels for full-speed operation before the sysrst is released. the power-up timer delay (t pwrt ) is programmed by the power-on reset timer value select (fpwrt<2:0>) bits in the por configuration (fpor<2:0>) register, which provides eight settings (from 0 ms to 128 ms). refer to section 24.0 ?special features? for further details. figure 6-3 shows the typical brown-out scenarios. the reset delay (t bor + t pwrt ) is initiated each time v dd rises above the v bor trip point figure 6-3: brown-o ut situations v dd sysrst v bor v dd sysrst v bor v dd sysrst v bor t bor + t pwrt v dd dips before pwrt expires t bor + t pwrt t bor + t pwrt dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 120 preliminary ? 2009 microchip technology inc. 6.4 external reset (extr) the external reset is generated by driving the mclr pin low. the mclr pin is a schmitt trigger input with an additional glitch filter. reset pulses that are longer than the minimum pulse width will generate a reset. refer to section 27.0 ?electrical characteristics? for minimum pulse width specifications. the external reset (mclr ) pin (extr) bit in the reset control (rcon) register is set to indicate the mclr reset. 6.4.0.1 external supervisory circuit many systems have external supervisory circuits that generate reset signals to reset multiple devices in the system. this external reset signal can be directly connected to the mclr pin to reset the device when the rest of system is reset. 6.4.0.2 internal supervisory circuit when using the internal power supervisory circuit to reset the device, the external reset pin (mclr ) should be tied directly or resistively to v dd . in this case, the mclr pin will not be used to generate a reset. the external reset pin (mclr ) does not have an internal pull-up and must not be left unconnected. 6.5 software reset instruction (swr) whenever the reset instruction is executed, the device will assert sysrst , placing the device in a special reset state. this reset state will not re-initialize the clock. the clock source in effect prior to the reset instruction will remain. sysrst is released at the next instruction cycle and the reset vector fetch will commence. the software reset (swr) flag (instruction) in the reset control (rcon<6>) register is set to indicate the software reset. 6.6 watchdog time-out reset (wdto) whenever a watchdog time-out occurs, the device will asynchronously assert sysrst . the clock source will remain unchanged. a wdt time-out during sleep or idle mode will wake-up the processor, but will not reset the processor. the watchdog timer time-out (wdto) flag in the reset control (rcon<4>) register is set to indicate the watchdog reset. refer to section 24.4 ?watchdog timer (wdt)? for more information on watchdog reset. 6.7 trap conflict reset if a lower priority hard trap occurs while a higher priority trap is being processed, a hard trap conflict reset occurs. the hard traps include exceptions of pri- ority level 13 through level 15, inclusive. the address error (level 13) and oscillator error (level 14) traps fall into this category. the trap reset (trapr) flag in the reset control (rcon<15>) register is set to indicate the trap conflict reset. refer to section 7.0 ?interrupt controller? for more information on trap conflict resets. 6.8 illegal condition device reset an illegal condition device reset occurs due to the following sources: ? illegal opcode reset ? uninitialized w register reset ? security reset the illegal opcode or uninitialized w access reset (iopuwr) flag in the reset control (rcon<14>) register is set to indicate the illegal condition device reset. 6.8.1 illegal opcode reset a device reset is generated if the device attempts to execute an illegal opcode value that is fetched from program memory. the illegal opcode reset function can prevent the device from executing program memory sections that are used to store constant data. to take advantage of the illegal opcode reset, use only the lower 16 bits of each program memory section to store the data values. the upper 8 bits should be programmed with 3fh, which is an illegal opcode value. 6.8.2 uninitialized w register reset any attempt to use the uninitialized w register as an address pointer will reset the device. the w register array (with the exception of w15) is cleared during all resets and is considered uninitialized until written to. 6.8.3 security reset if a program flow change (pfc) or vector flow change (vfc) targets a restricted location in a protected segment (boot and secure segment), that operation will cause a security reset. the pfc occurs when the program counter is reloaded as a result of a call, jump, computed jump, return, return from subroutine or other form of branch instruction. the vfc occurs when the program counter is reloaded with an interrupt or trap vector. refer to section 24.8 ?code protection and codeguard? security? for more information on security reset. ? 2009 microchip technology inc. preliminary ds70591b-page 121 dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 6.9 using the rcon status bits the user application can read the reset control (rcon) register after any device reset to determine the cause of the reset. table 6-2 provides a summary of the reset flag bit operation. table 6-2: reset flag bit operation note: the status bits in the rcon register should be cleared after they are read so that the next rcon register value after a device reset will be meaningful. flag bit set by: cleared by: trapr (rcon<15>) trap conflict event por,bor iopwr (rcon<14>) illegal opcode or uninitialized w register access or security reset por,bor extr (rcon<7>) mclr reset por swr (rcon<6>) reset instruction por,bor wdto (rcon<4>) wdt time-out pwrsav instruction, clrwdt instruction, por,bor sleep (rcon<3>) pwrsav #sleep instruction por,bor idle (rcon<2>) pwrsav #idle instruction por,bor bor (rcon<1>) por, bor por (rcon<0>) por note: all reset flag bits can be set or cleared by user software. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 122 preliminary ?

up to eight processor exceptions and software traps ? seven user-selectable priority levels ? interrupt vector table (ivt) with up to 118 vectors ? a unique vector for each interrupt or exception source ? fixed priority within a specified user priority level ? alternate interrupt vector table (aivt) for debug support ? fixed interrupt entry and return latencies 7.1 interrupt vector table the interrupt vector table (ivt) is shown in figure 7-1. the ivt resides in program memory, starting at location 000004h. the ivt contains 126 vectors, consisting of eight nonmaskable trap vectors, plus up to 118 sources of interrupt. in general, each interrupt source has its own vector. each interrupt vector contains a 24-bit-wide address. the value programmed into each interrupt vector location is the starting address of the associated interrupt service routine (isr). interrupt vectors are prioritized in terms of their natural priority. this priority is linked to their position in the vector table. lower addresses generally have a higher natural priority. for example, the interrupt associated with vector 0 will take priority over interrupts at any other vector address. the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/ 610 devices implement up to 71 unique interrupts and five non-maskable traps. these are summarized in table 7-1. 7.1.1 alternate interrupt vector ta b l e the alternate interrupt vector table (aivt) is located after the ivt, as shown in figure 7-1. access to the aivt is provided by the altivt control bit (intcon2<15>). if the altivt bit is set, all interrupt and exception processes use the alternate vectors instead of the default vectors. the alternate vectors are organized in the same manner as the default vectors. the aivt supports debugging by providing a means to switch between an application and a support environment without requiring the interrupt vectors to be reprogrammed. this feature also enables switching between applications for evaluation of different software algorithms at run time. if the aivt is not needed, the aivt should be programmed with the same addresses used in the ivt. 7.2 reset sequence a device reset is not a true exception because the interrupt controller is not involved in the reset process. the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 device clears its registers in response to a reset, which forces the pc to zero. the digital signal controller then begins program execution at location 0x000000. a goto instruction at the reset address can redirect program execution to the appropriate start-up routine. note 1: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 47. ?interrupts (part v)?

intcon1 ? intcon2 ?ifsx ?iecx ?ipcx ?inttreg 7.3.1 intcon1 and intcon2 global interrupt control functions are controlled from intcon1 and intcon2. intcon1 contains the interrupt nesting disable (nstdis) bit as well as the control and status flags for the processor trap sources. the intcon2 register controls the external interrupt request signal behavior and the use of the alternate interrupt vector table. 7.3.2 ifsx the ifsx registers maintain all of the interrupt request flags. each source of interrupt has a status bit, which is set by the respective peripherals or external signal and is cleared via software. 7.3.3 iecx the iecx registers maintain all of the interrupt enable bits. these control bits are used to individually enable interrupts from the peripherals or external signals. 7.3.4 ipcx the ipcx registers are used to set the interrupt priority level for each source of interrupt. each user interrupt source can be assigned to one of eight priority levels. 7.3.5 inttreg the inttreg register contains the associated interrupt vector number and the new cpu interrupt priority level, which are latched into the vector number (vecnum<6:0>) and interrupt level (ilr<3:0>) bit fields in the inttreg register. the new interrupt priority level is the priority of the pending interrupt. the interrupt sources are assigned to the ifsx, iecx and ipcx registers in the same sequence that they are listed in table 7-1. for example, the int0 (external interrupt 0) is shown as having vector number 8 and a natural order priority of 0. thus, the int0if bit is found in ifs0<0>, the int0ie bit is found in iec0<0> and the int0ip bits are found in the first position of ipc0 (ipc0<2:0>). 7.3.6 status/control registers although they are not specifically part of the interrupt control hardware, two of the cpu control registers contain bits that control interrupt functionality. ? the cpu status register, sr, contains the ipl<2:0> bits (sr<7:5>). these bits indicate the current cpu interrupt priority level. the user can change the current cpu priority level by writing to the ipl bits. ? the corcon register contains the ipl3 bit, which together with ipl<2:0>, indicates the current cpu priority level. ipl3 is a read-only bit so that trap events cannot be masked by the user software. all interrupt registers are described in register 7-1 through register 7-46 in the following pages. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 128 preliminary ?

2009 microchip technology inc. 7.4 interrupt setup procedures 7.4.1 initialization complete the following steps to configure an interrupt source at initialization: 1. set the nstdis bit (intcon1<15>) if nested interrupts are not desired. 2. select the user-assigned priority level for the interrupt source by writing the control bits in the appropriate ipcx register. the priority level will depend on the specific application and type of interrupt source. if multiple priority levels are not desired, the ipcx register control bits for all enabled interrupt sources can be programmed to the same non-zero value. 3. clear the interrupt flag status bit associated with the peripheral in the associated ifsx register. 4. enable the interrupt source by setting the interrupt enable control bit associated with the source in the appropriate iecx register. 7.4.2 interrupt service routine the method used to declare an isr and initialize the ivt with the correct vector address depends on the programming language (c or assembler) and the language development toolsuite used to develop the application. in general, the user application must clear the interrupt flag in the appropriate ifsx register for the source of interrupt that the isr handles. otherwise, program will re-enter the isr immediately after exiting the routine. if the isr is coded in assembly language, it must be terminated using a retfie instruction to unstack the saved pc value, srl value and old cpu priority level. 7.4.3 trap service routine a trap service routine (tsr) is coded like an isr, except that the appropriate trap status flag in the intcon1 register must be cleared to avoid re-entry into the tsr. 7.4.4 interrupt disable the following steps outline the procedure to disable all user interrupts: 1. push the current sr value onto the software stack using the push instruction. 2. force the cpu to priority level 7 by inclusive oring the value eoh with srl. to enable user interrupts, the pop instruction can be used to restore the previous sr value. the disi instruction provides a convenient way to disable interrupts of priority levels 1-6 for a fixed period of time. level 7 interrupt sources are not disabled by the disi instruction. note: at a device reset, the ipcx registers are initialized such that all user interrupt sources are assigned to priority level 4. note: only user interrupts with a priority level of 7 or lower can be disabled. trap sources (level 8-level 15) cannot be disabled. ?

word or byte sized data transfers. ? transfers from peripheral to dma ram or dma ram to peripheral. ? indirect addressing of dma ram locations with or without automatic post-increment. ? peripheral indirect addressing ? in some peripherals, the dma ram read/write addresses may be partially derived from the peripheral. ? one-shot block transfers ? terminating dma transfer after one block transfer. ? continuous block transfers ? reloading dma ram buffer start address after every block transfer is complete. ? ping-pong mode ? switching between two dma ram start addresses between successive block transfers, thereby filling two buffers alternately. ? automatic or manual initiation of block transfers. for each dma channel, a dma interrupt request is generated when a block transfer is complete. alternatively, an interrupt can be generated when half of the block has been filled. 8.1 dmac registers each dmac channel x (x = 0, 1, 2, or 3) contains the following registers: ? a 16-bit dma channel control register (dmaxcon) ? a 16-bit dma channel irq select register (dmaxreq) ? a 16-bit dma ram primary start address offset register (dmaxsta) ? a 16-bit dma ram secondary start address offset register (dmaxstb) ? a 16-bit dma peripheral address register (dmaxpad) ? a 10-bit dma transfer count register (dmaxcnt) an additional pair of status registers, dmacs0 and dmacs1, are common to all dmac channels. figure 8-1: top level system architecture using a dedicated transaction bus cpu sram dma ram cpu peripheral ds bus peripheral 3 dma peripheral non-dma sram x-bus port 2 port 1 peripheral 1 dma ready peripheral 2 dma ready ready ready dma ds bus cpu dma cpu dma cpu dma peripheral indirect address note: for clarity, cpu and dma address buses are not shown. dma control dma controller dma channels 01 23 ?

(refer to section 24.1 ?configuration bits? for further details.) the initial oscillator selection configuration bits, fnosc<2:0> (foscsel<2:0>), and the primary oscillator mode select configuration bits, poscmd<1:0> (fosc<1:0>), select the oscillator source that is used at a power-on reset. the frc primary oscillator is the default (unprogrammed) selection. the configuration bits allow users to choose among 12 different clock modes, shown in table 9-1. the output of the oscillator (or the output of the pll if a pll mode has been selected), f osc , is divided by 2 to generate the device instruction clock (f cy ) and the peripheral clock time base (f p ). f cy defines the operating speed of the device and speeds up to 40 mhz are supported by the dspic33fj32gs406/606/ 608/610 and dspic33fj64gs406/606/608/610 architecture. instruction execution speed or device operating frequency, f cy , is given by equation 9-1. equation 9-1: device operating frequency f cy = f osc /2 dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 190 preliminary ? 2009 microchip technology inc. table 9-1: configuration bit va lues for clock selection 9.1.3 pll configuration the primary oscillator and internal frc oscillator can optionally use an on-chip pll to obtain higher speeds of operation. the pll provides significant flexibility in selecting the device operating speed. a block diagram of the pll is shown in figure 9-2. the output of the primary oscillator or frc, denoted as ?f in ?, is divided down by a prescale factor (n1) of 2, 3, ... or 33 before being provided to the pll?s voltage controlled oscillator (vco). the input to the vco must be selected in the range of 0.8 mhz to 8 mhz. the prescale factor ?n1? is selected using the pllpre<4:0> bits (clkdiv<4:0>). the pll feedback divisor, selected using the plldiv<8:0> bits (pllfbd<8:0>), provides a factor, ?m?, by which the input to the vco is multiplied. this factor must be selected such that the resulting vco output frequency is in the range of 100 mhz to 200 mhz. the vco output is further divided by a postscale factor, ?n2?. this factor is selected using the pllpost<1:0> bits (clkdiv<7:6>). ?n2? can be either 2, 4 or 8, and must be selected such that the pll output frequency (f osc ) is in the range of 12.5 mhz to 80 mhz, which generates device operating speeds of 6.25-40 mips. for a primary oscillator or frc oscillator, output ?f in ?, the pll output ?f osc ? is given by equation 9-2. equation 9-2: f osc calculation for example, suppose a 10 mhz crystal is being used with the selected oscillator mode of xt with pll (see equation 9-3). ? if pllpre<4:0> = 0 , then n1 = 2. this yields a vco input of 10/2 = 5 mhz, which is within the acceptable range of 0.8-8 mhz. ? if plldiv<8:0> = 0x1e, then m = 32. this yields a vco output of 5 x 32 = 160 mhz, which is within the 100-200 mhz ranged needed. ? if pllpost<1:0> = 0 , then n2 = 2. this provides a f osc of 160/2 = 80 mhz. the resultant device operating speed is 80/2 = 40 mips. equation 9-3: xt with pll mode example oscillator mode oscillator source poscmd<1:0> fnosc<2:0> note fast rc oscillator with divide-by-n (frcdivn) internal xx 111 1, 2 fast rc oscillator with divide-by-16 (frcdiv16) internal xx 110 1 low-power rc oscillator (lprc) internal xx 101 1 secondary oscillator (sosc) secondary xx 100 ? primary oscillator (hs) with pll (hspll) primary 10 011 ? primary oscillator (xt) with pll (xtpll) primary 01 011 ? primary oscillator (ec) with pll (ecpll) primary 00 011 1 primary oscillator (hs) primary 10 010 ? primary oscillator (xt) primary 01 010 ? primary oscillator (ec) primary 00 010 1 fast rc oscillator with pll (frcpll) internal xx 001 1 fast rc oscillator (frc) internal xx 000 1 note 1: osc2 pin function is determined by the osciofnc configuration bit. 2: this is the default oscillator mode for an unprogrammed (erased) device.

0 ?. (refer to section 24.1 ?configuration bits? for further details.) if the fcksm1 configuration bit is unprogrammed (? 1 ?), the clock switching function and fail-safe clock monitor function are disabled. this is the default setting. the nosc control bits (osccon<10:8>) do not control the clock selection when clock switching is disabled. however, the cosc bits (osccon<14:12>) reflect the clock source selected by the fnosc configuration bits. the oswen control bit (osccon<0>) has no effect when clock switching is disabled. it is held at ? 0 ? at all times. 9.4.2 oscillator switching sequence to perform a clock switch, the following basic sequence is required: 1. if desired, read the cosc bits (osccon<14:12>) to determine the current oscillator source. 2. perform the unlock sequence to allow a write to the osccon register high byte. 3. write the appropriate value to the nosc control bits (osccon<10:8>) for the new oscillator source. 4. perform the unlock sequence to allow a write to the osccon register low byte. 5. set the oswen bit (osccon<0>) to initiate the oscillator switch. once the basic sequence is completed, the system clock hardware responds automatically as follows: 1. the clock switching hardware compares the cosc status bits with the new value of the nosc control bits. if they are the same, the clock switch is a redundant operation. in this case, the oswen bit is cleared automatically and the clock switch is aborted. 2. if a valid clock switch has been initiated, the lock (osccon<5>) and the cf (osccon<3>) status bits are cleared. 3. the new oscillator is turned on by the hardware if it is not currently running. if a crystal oscillator must be turned on, the hardware waits until the oscillator start-up timer (ost) expires. if the new source is using the pll, the hardware waits until a pll lock is detected (lock = 1 ). 4. the hardware waits for 10 clock cycles from the new clock source and then performs the clock switch. 5. the hardware clears the oswen bit to indicate a successful clock transition. in addition, the nosc bit values are transferred to the cosc status bits. 6. the old clock source is turned off at this time, with the exception of lprc (if wdt or fscm are enabled) or lp (if lposcen remains set). 9.5 fail-safe clock monitor (fscm) the fail-safe clock monitor (fscm) allows the device to continue to operate even in the event of an oscillator failure. the fscm function is enabled by programming. if the fscm function is enabled, the lprc internal oscillator runs at all times (except during sleep mode) and is not subject to control by the watchdog timer. in the event of an oscillator failure, the fscm generates a clock failure trap event and switches the system clock over to the frc oscillator. then, the application program can either attempt to restart the oscillator or execute a controlled shutdown. the trap can be treated as a warm reset by simply loading the reset address into the oscillator fail trap vector. if the pll multiplier is used to scale the system clock, the internal frc is also multiplied by the same factor on clock failure. essentially, the device switches to frc with pll on a clock failure. note: primary oscillator mode has three different submodes (xt, hs and ec), which are determined by the poscmd<1:0> configuration bits. while an application can switch to and from primary oscillator mode in software, it cannot switch among the different primary submodes without reprogramming the device. note 1: the processor continues to execute code throughout the clock switching sequence. timing-sensitive code should not be executed during this time. 2: direct clock switches between any primary oscillator mode with pll and frcpll mode are not permitted. this applies to clock switches in either direction. in these instances, the application must switch to frc mode as a transition clock source between the two pll modes. 3: refer to section 42. ?oscillator (part iv)?

2009 microchip technology inc. 10.2.2 idle mode the following occur in idle mode: ? the cpu stops executing instructions. ? the wdt is automatically cleared. ? the system clock source remains active. by default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see section 10.5 ?peripheral module disable? ). ? if the wdt or fscm is enabled, the lprc also remains active. the device will wake-up from idle mode on any of these events: ? any interrupt that is individually enabled ? any device reset ? a wdt time-out on wake-up from idle mode, the clock is reapplied to the cpu and instruction execution will begin (2-4 clock cycles later), starting with the instruction following the pwrsav instruction, or the first instruction in the isr. 10.2.3 interrupts coincident with power save instructions any interrupt that coincides with the execution of a pwrsav instruction is held off until entry into sleep or idle mode has completed. the device then wakes up from sleep or idle mode. 10.3 doze mode the preferred strategies for reducing power consumption are changing clock speed and invoking one of the power-saving modes. in some circumstances, this may not be practical. for example, it may be necessary for an application to maintain uninterrupted synchronous communication, even while it is doing nothing else. reducing system clock speed can introduce communication errors, while using a power-saving mode can stop communications completely. doze mode is a simple and effective alternative method to reduce power consumption while the device is still executing code. in this mode, the system clock continues to operate from the same source and at the same speed. peripheral modules continue to be clocked at the same speed, while the cpu clock speed is reduced. synchronization between the two clock domains is maintained, allowing the peripherals to access the sfrs while the cpu executes code at a slower rate. doze mode is enabled by setting the dozen bit (clkdiv<11>). the ratio between peripheral and core clock speed is determined by the doze<2:0> bits (clkdiv<14:12>). there are eight possible configurations, from 1:1 to 1:128, with 1:1 being the default setting. programs can use doze mode to selectively reduce power consumption in event-driven applications. this allows clock-sensitive functions, such as synchronous communications, to continue without interruption while the cpu idles, waiting for something to invoke an interrupt routine. an automatic return to full-speed cpu operation on interrupts can be enabled by setting the roi bit (clkdiv<15>). by default, interrupt events have no effect on doze mode operation. for example, suppose the device is operating at 20 mips and the can module has been configured for 500 kbps based on this device operating speed. if the device is placed in doze mode with a clock frequency ratio of 1:4, the can module continues to communicate at the required bit rate of 500 kbps, but the cpu now starts executing instructions at a frequency of 5 mips. 10.4 pwm power-saving features typically, many applications need either a high resolution duty cycle or phase offset (for fixed frequency operation) or a high resolution pwm period for variable frequency modes of operation (such as resonant mode). very few applications require both high resolution modes simultaneously. the hrpdis and the hrddis bits in the auxconx registers permit the user to disable the circuitry associ- ated with the high resolution duty cycle and pwm period to reduce the operating current of the device. if the hrddis bit is set, the circuitry associated with the high resolution duty cycle, phase offset, and dead time for the respective pwm generator is disabled. if the hrpdis bit is set, the circuitry associated with the high resolution pwm period for the respective pwm generator is disabled. when the hrpdis bit is set, the smallest unit of measure for the pwm period is 8.32 ns. if the hrddis bit is set, the smallest unit of measure for the pwm duty cycle, phase offset and dead time is 8.32 ns. ?

dsc variant. if the peripheral is present in the device, it is enabled in the pmd register by default. note: if a pmd bit is set, the corresponding module is disabled after a delay of one instruction cycle. similarly, if a pmd bit is cleared, the corresponding module is enabled after a delay of one instruction cycle (assuming the module control regis- ters are already configured to enable module operation). dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 202 preliminary ?

1 ?, then the pin is an input. all port pins are defined as inputs after a reset. reads from the latch (latx) read the latch. writes to the latch write the latch. reads from the port (portx) read the port pins, while writes to the port pins write the latch. any bit and its associated data and control registers that are not valid for a particular device will be disabled. that means the corresponding latx and trisx registers and the port pin will read as zeros. when a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other competing source of outputs. figure 11-1: block diagram of a typical shared port structure note 1: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 10. ?i/o ports?

2009 microchip technology inc. 11.2 open-drain configuration in addition to the port, lat and tris registers for data control, some digital-only port pins can also be individually configured for either digital or open-drain output. this is controlled by the open-drain control register, odcx, associated with each port. setting any of the bits configures the corresponding pin to act as an open-drain output. the open-drain feature allows the generation of outputs higher than v dd (for example, 5v) on any desired 5v tolerant pins by using external pull-up resistors. the maximum open-drain voltage allowed is the same as the maximum v ih specification. refer to ?pin diagrams? for the available pins and their functionality. 11.3 configuring analog port pins the adpcfg and tris registers control the operation of the analog-to-digital (a/d) port pins. the port pins that are to function as analog inputs must have their corresponding tris bit set (input). if the tris bit is cleared (output), the digital output level (v oh or v ol ) will be converted. the adpcfg and adpcfg2 registers have a default value of 0x000; therefore, all pins that share anx functions are analog (not digital) by default. when the port register is read, all pins configured as analog input channels will read as cleared (a low level). pins configured as digital inputs will not convert an analog input. analog levels on any pin defined as a digital input (including the anx pins) can cause the input buffer to consume current that exceeds the device specifications. 11.4 i/o port write/read timing one instruction cycle is required between a port direction change or port write operation and a read operation of the same port. typically, this instruction would be a nop . an example is shown in example 11-1. 11.5 input change notification the input change notification function of the i/o ports allows the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices to gen- erate interrupt requests to the processor in response to a change-of-state (cos) on selected input pins. this feature can detect input change-of-states even in sleep mode, when the clocks are disabled. depending on the device pin count, up to 30 external signals (cnx pin) can be selected (enabled) for generating an interrupt request on a change-of-state. four control registers are associated with the cn module. the cnen1 and cnen2 registers contain the interrupt enable control bits for each of the cn input pins. setting any of these bits enables a cn interrupt for the corresponding pins. each cn pin also has a weak pull-up connected to it. the pull-ups act as a current source connected to the pin, and eliminate the need for external resistors when the push button or keypad devices are connected. the pull-ups are enabled separately using the cnpu1 and cnpu2 registers, which contain the control bits for each of the cn pins. setting any of the control bits enables the weak pull-ups for the corresponding pins. equation 11-1: port write/read example note: pull-ups on change notification pins should always be disabled when the port pin is configured as a digital output. mov 0xff00, w0 ; configure portb<15:8> as inputs mov w0, trisbb ; and portb<7:0> as outputs nop ; delay 1 cycle btss portb, #13 ; next instruction ?

can be operated from the low-power 32.767 khz crystal oscillator available on the device ? can be operated in asynchronous counter mode from an external clock source. ? the external clock input (t1ck) can optionally be synchronized to the internal device clock and the clock synchronization is performed after the prescaler. the unique features of timer1 allow it to be used for real-time clock (rtc) applications. a block diagram of timer1 is shown in figure 12-1. the timer1 module can operate in one of the following modes: ? timer mode ? gated timer mode ? synchronous counter mode ? asynchronous counter mode in timer and gated timer modes, the input clock is derived from the internal instruction cycle clock (f cy ). in synchronous and asynchronous counter modes, the input clock is derived from the external clock input at the t1ck pin. the timer modes are determined by the following bits: ? timer clock source control bit (tcs): t1con<1> ? timer synchronization control bit (tsync): t1con<2> ? timer gate control bit (tgate): t1con<6> the timer control bit settings for different operating modes are given in the table 12-1. table 12-1: timer mode settings figure 12-1: 16-bit time r1 module block diagram note 1: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 11. ?timers?

simple capture event modes: - capture timer value on every falling edge of input at icx pin - capture timer value on every rising edge of input at icx pin ? capture timer value on every edge (rising and falling) ? prescaler capture event modes: - capture timer value on every 4th rising edge of input at icx pin - capture timer value on every 16th rising edge of input at icx pin each input capture channel can select one of the two 16-bit timers (timer2 or timer3) for the time base. the selected timer can use either an internal or external clock. other operational features include: ? device wake-up from capture pin during cpu sleep and idle modes ? interrupt on input capture event ? 4-word fifo buffer for capture values - interrupt optionally generated after 1, 2, 3 or 4 buffer locations are filled ?

ac/dc converters ? dc/dc converters ? power factor correction ? uninterruptible power supply (ups) ? inverters ? battery chargers ? digital lighting 16.1 features overview the high-speed pwm module incorporates the following features: ? two master time base modules ? up to nine pwm generators with up to 18 outputs ? two pwm outputs per pwm generator ? individual time base and duty cycle for each pwm output ? duty cycle, dead time, phase shift, and frequency resolution of 1.04 ns at 40 mips ? independent fault and current-limit inputs for eight pwm outputs ? redundant output ? true independent output ? center-aligned pwm mode ? output override control ? chop mode (also known as gated mode) ? special event trigger ? prescaler for input clock ? dual trigger from pwm to analog-to-digital con- verter (adc) per pwm period ? pwmxl and pwmxh output pin swapping ? independent pwm frequency, duty cycle, and phase shift changes ? current compensation ? enhanced leading-edge blanking (leb) functionality ? pwm capture functionality figure 16-1 conceptualizes the pwm module in a simplified block diagram. figure 16-2 illustrates how the module hardware is partitioned for each pwm output pair for the complementary pwm mode. the pwm module contains nine pwm generators. the module has up to 18 pwm output pins: pwm1h, pwm1l, pwm2h, pwm2l, pwm3h, pwm3l, pwm4h, pwm4l, pwm5h, pwm5l, pwm6h, pwm6l, pwm7h, pwm7l, pwm8h, pwm8l, pwm9h, and pwm9l. for complementary outputs, these 18 i/o pins are grouped into h/l pairs. 16.2 feature description the pwm module is designed for applications that require: ? high-resolution at high pwm frequencies ? the ability to drive standard, edge-aligned, center-aligned complementary mode, and push-pull mode outputs ? the ability to create multiphase pwm outputs for center-aligned mode, the duty cycle, period phase and dead-time resolutions will be 8.32 ns. two common, medium power converter topologies are push-pull and half-bridge. these designs require the pwm output signal to be switched between alternate pins, as provided by the push-pull pwm mode. phase-shifted pwm describes the situation where each pwm generator provides outputs, but the phase relationship between the generator outputs is specifiable and changeable. multiphase pwm is often used to improve dc/dc con- verter load transient response, and reduce the size of output filter capacitors and inductors. multiple dc/dc converters are often operated in parallel, but phase-shifted in time. a single pwm output operating at 250 khz has a period of 4 ? s, but an array of four pwm channels, staggered by 1 ? s each, yields an effective switching frequency of 1 mhz. multiphase pwm applications typically use a fixed-phase relationship. variable phase pwm is useful in zero voltage transition (zvt) power converters. here, the pwm duty cycle is always 50%, and the power flow is con- trolled by varying the relative phase shift between the two pwm generators. note 1: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 50. ?high-speed pwm?

the sclx pin is clock. ? the sdax pin is data. the i 2 c module offers the following key features: ?i 2 c interface supporting both master and slave modes of operation. ?i 2 c slave mode supports 7-bit and 10-bit addressing. ?i 2 c master mode supports 7-bit and 10-bit addressing. ?i 2 c port allows bidirectional transfers between master and slaves. ? serial clock synchronization for i 2 c port can be used as a handshake mechanism to suspend and resume serial transfer (sclrel control). ?i 2 c supports multi-master operation, detects bus collision and arbitrates accordingly. 19.1 operating modes the hardware fully implements all the master and slave functions of the i 2 c standard and fast mode specifications, as well as 7-bit and 10-bit addressing. the i 2 c module can operate either as a slave or a master on an i 2 c bus. the following types of i 2 c operation are supported: ?i 2 c slave operation with 7-bit addressing ?i 2 c slave operation with 10-bit addressing ?i 2 c master operation with 7-bit or 10-bit addressing for details about the communication sequence in each of these modes, refer to the ? dspic33f/pic24h family reference manual ?. please see the microchip web site (www.microchip.com) for the latest ?dspic33f/pic24h family reference manual ? chapters. 19.2 i 2 c registers i2cxcon and i2cxstat are control and status registers, respectively. the i2cxcon register is readable and writable. the lower six bits of i2cxstat are read-only. the remaining bits of the i2cstat are read/write: ? i2cxrsr is the shift register used for shifting data internal to the module and the user application has no access to it. ? i2cxrcv is the receive buffer and the register to which data bytes are written, or from which data bytes are read. ? i2cxtrn is the transmit register to which bytes are written during a transmit operation. ? the i2cxadd register holds the slave address. ? a status bit, add10, indicates 10-bit address mode. ? the i2cxbrg acts as the baud rate generator (brg) reload value. in receive operations, i2cxrsr and i2cxrcv together form a double-buffered receiver. when i2cxrsr receives a complete byte, it is transferred to i2cxrcv, and an interrupt pulse is generated. note 1: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 19. ?inter-inte- grated circuit (i 2 c?)?

initialization mode ? disable mode ? normal operation mode ? listen only mode ? listen all messages mode ? loopback mode modes are requested by setting the reqop<2:0> bits (cictrl1<10:8>). entry into a mode is acknowledged by monitoring the opmode<2:0> bits (cictrl1<7:5>). the module does not change the mode and the opmode bits until a change in mode is acceptable, generally during bus idle time, which is defined as at least 11 consecutive recessive bits. 21.3.1 initialization mode in the initialization mode, the module does not transmit or receive. the error counters are cleared and the inter- rupt flags remain unchanged. the user application has access to configuration registers that are access restricted in other modes. the module protects the user from accidentally violating the can protocol through programming errors. all registers which control the configuration of the module can not be modified while the module is on-line. the ecan module is not allowed to enter the configuration mode while a transmission is taking place. the configuration mode serves as a lock to protect the following registers: ? all module control registers ? baud rate and interrupt configuration registers ? bus timing registers ? identifier acceptance filter registers ? identifier acceptance mask registers 21.3.2 disable mode in disable mode, the module does not transmit or receive. the module has the ability to set the wakif bit due to bus activity, however, any pending interrupts remains and the error counters retains their value. if the reqop<2:0> bits (cictrl1<10:8>) = 001 , the module enters the module disable mode. if the module is active, the module waits for 11 recessive bits on the can bus, detect that condition as an idle bus, then accept the module disable command. when the opmode<2:0> bits (cictrl1<7:5>) = 001 , that indicates whether the module successfully went into module disable mode. the i/o pins reverts to normal i/o function when the module is in the module disable mode. the module can be programmed to apply a low-pass filter function to the cirx input line while the module or the cpu is in sleep mode. the wakfil bit (cicfg2<14>) enables or disables the filter. 21.3.3 normal operation mode normal operation mode is selected when reqop<2:0> = 000 . in this mode, the module is activated and the i/o pins assumes the can bus functions. the module transmits and receive can bus messages via the citx and cirx pins. 21.3.4 listen only mode if the listen only mode is activated, the module on the can bus is passive. the transmitter buffers revert to the port i/o function. the receive pins remain inputs. for the receiver, no error flags or acknowledge signals are sent. the error counters are deactivated in this state. the listen only mode can be used for detecting the baud rate on the can bus. to use this, it is neces- sary that there are at least two further nodes that communicate with each other. 21.3.5 listen all messages mode the module can be set to ignore all errors and receive any message. the listen all messages mode is acti- vated by setting reqop<2:0> = ? 111 ?. in this mode, the data which is in the message assembly buffer, until the time an error occurred, is copied in the receive buf- fer and can be read via the cpu interface. 21.3.6 loopback mode if the loopback mode is activated, the module con- nects the internal transmit signal to the internal receive signal at the module boundary. the transmit and receive pins revert to their port i/o function. note: typically, if the ecan module is allowed to transmit in a particular mode of operation and a transmission is requested immedi- ately after the ecan module has been placed in that mode of operation, the mod- ule waits for 11 consecutive recessive bits on the bus before starting transmission. if the user switches to disable mode within this 11-bit period, then this transmission is aborted and the corresponding txabt bit is set and txreq bit is cleared. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 282 preliminary ?

10-bit resolution ? unipolar inputs ? up to two successive approximation registers (sars) ? up to 24 external input channels ? two internal analog inputs ? dedicated result register for each analog input ? 1 lsb accuracy at 3.3v ? single supply operation ? 4 msps conversion rate at 3.3v (devices with two sars) ? 2 msps conversion rate at 3.3v (devices with one sar) ? low-power cmos technology 22.2 module description this adc module is designed for applications that require low latency between the request for conversion and the resultant output data. typical applications include: ? ac/dc power supplies ? dc/dc converters ? power factor correction (pfc) this adc works with the high-speed pwm module in power control applications that require high-frequency control loops. this module can sample and convert two analog inputs in a 0.5 microsecond when two sars are used. this small conversion delay reduces the ?phase lag? between measurement and control system response. up to five inputs may be sampled at a time (four inputs from the dedicated sample and hold circuits and one from the shared sample and hold circuit). if multiple inputs request conversion, the adc will convert them in a sequential manner, starting with the lowest order input. this adc design provides each pair of analog inputs (an1,an0), (an3,an2),..., the ability to specify its own trigger source out of a maximum of sixteen different trigger sources. this capability allows this adc to sample and convert analog inputs that are associated with pwm generators operating on independent time bases. the user application typically requires synchronization between analog data sampling and pwm output to the application circuit. the very high-speed operation of this adc module allows ?data on demand?. in addition, several hardware features have been added to the peripheral interface to improve real-time performance in a typical dsp-based application. ? result alignment options ? automated sampling ? external conversion start control ? two internal inputs to monitor 1.2v internal reference and extref input signal a block diagram of the adc module is shown in figure 22-2. note 1: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 families of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to section 44. ?high-speed 10-bit analog-to-digital converter (adc)? (ds70321) in the ?dspic33f/pic24h family reference manual? , which is available from the microchip web site (www.microchip.com). 2: some registers and associated bits described in this section may not be avail- able on all devices. refer to section 4.0 ?memory organization?

adcon: a/d control register ? adstat: a/d status register ? adbase: a/d base register ? adpcfg: a/d port configuration register ? adpcfg2: a/d port configuration register 2 ? adcpc0: a/d convert pair control register 0 ? adcpc1: a/d convert pair control register 1 ? adcpc2: a/d convert pair control register 2 ? adcpc3: a/d convert pair control register 3 ? adcpc4: a/d convert pair control register 4 ? adcpc5: a/d convert pair control register 5 ? adcpc6: a/d convert pair control register 6 the adcon register controls the operation of the adc module. the adstat register displays the status of the conversion processes. the adpcfg registers configure the port pins as analog inputs or as digital i/o. the adcpcx registers control the triggering of the adc conversions. see register 22-1 through register 22-12 for detailed bit configurations. note: a unique feature of the adc module is its ability to sample inputs in an asynchronous manner. individual sample and hold circuits can be triggered independently of each other. ?

2009 microchip technology inc. 23.3 module applications this module provides a means for the smps dspic dsc devices to monitor voltage and currents in a power conversion application. the ability to detect transient conditions and stimulate the dspic dsc processor and/or peripherals, without requiring the processor and adc to constantly monitor voltages or currents, frees the dspic dsc to perform other tasks. the comparator module has a high-speed comparator and an associated 10-bit dac that provides a programmable reference voltage to the inverting input of the comparator. the polarity of the comparator out- put is user-programmable. the output of the module can be used in the following modes: ? generate an interrupt ? trigger an adc sample and convert process ? truncate the pwm signal (current limit) ? truncate the pwm period (current minimum) ? disable the pwm outputs (fault latch) the output of the comparator module may be used in multiple modes at the same time, such as: (1) generate an interrupt, (2) have the adc take a sample and convert it, and (3) truncate the pwm output in response to a voltage being detected beyond its expected value. the comparator module can also be used to wake-up the system from sleep or idle mode when the analog input voltage exceeds the programmed threshold voltage. 23.4 dac the range of the dac is controlled via an analog multiplexer that selects either av dd /2, internal 1.2v, 1% reference, or an external reference source, extref. the full range of the dac (av dd /2) will typically be used when the chosen input source pin is shared with the adc. the reduced range option (intref) will likely be used when monitoring current levels using a current sense resistor. usually, the measured voltages in such applications are small (<1.25v); therefore the option of using a reduced reference range for the comparator extends the available dac resolution in these applications. the use of an external reference enables the user to connect to a reference that better suits their application. dacout, shown in figure 23-1, can only be associated with a single comparator at a given time. 23.5 interaction with i/o buffers if the comparator module is enabled and a pin has been selected as the source for the comparator, then the chosen i/o pad must disable the digital input buffer associated with the pad to prevent excessive currents in the digital buffer due to analog input voltages. 23.6 digital logic the cmpconx register (see register 23-1) provides the control logic that configures the comparator module. the digital logic provides a glitch filter for the comparator output to mask transient signals in less than two instruction cycles. in sleep or idle mode, the glitch filter is bypassed to enable an asynchronous path from the comparator to the interrupt controller. this asynchronous path can be used to wake-up the processor from sleep or idle mode. the comparator can be disabled while in idle mode if the cmpsidl bit is set. if a device has multiple comparators, if any cmpsidl bit is set, then the entire group of comparators will be disabled while in idle mode. this behavior reduces complexity in the design of the clock control logic for this module. the digital logic also provides a one t cy width pulse generator for triggering the adc and generating interrupt requests. the cmpdacx (see register 23-2) register provides the digital input value to the reference dac. if the module is disabled, the dac and comparator are disabled to reduce power consumption. 23.7 comparator input range the comparator has a limitation for the input common mode range (cmr) of (av dd ? 1.5v), typical. this means that both inputs should not exceed this range. as long as one of the inputs is within the common mode range, the comparator output will be correct. however, any input exceeding the cmr limitation will cause the comparator input to be saturated. if both inputs exceed the cmr, the comparator output will be indeterminate. 23.8 dac output range the dac has a limitation for the maximum reference voltage input of (av dd ? 1.6) volts. an external reference voltage input should not exceed this value or the reference dac output will become indeterminate. 23.9 comparator registers the comparator module is controlled by the following registers: ? cmpconx: comparator control register ? cmpdacx: comparator dac control register note: it should be ensured in software that multiple dacoe bits are not set. the output on the dacout pin will be indeter- minate if multiple comparators enable the dac output. ?

. on a por , it takes approximately 20 ? s for the on-chip voltage regulator to generate an output voltage. during this time, designated as t startup , code execution is disabled. t startup is applied every time the device resumes operation after any power-down. figure 24-1: conne ctions for the on-chip voltage regulator (1,2) cmppol1 fcmp comparator hysteresis polarity (for odd numbered comparators) 1 = hysteresis is applied to falling edge 0 = hysteresis is applied to rising edge hyst1<1:0> fcmp comparator hysteresis select 11 = 45 mv hysteresis 10 = 30 mv hysteresis 01 = 15 mv hysteresis 00 = no hysteresis table 24-2: dspic33f configuration bits description (continued) bit field register description note: it is important for the low-esr capacitor to be placed as close as possible to the v cap /v ddcore pin. note 1: these are typical operating voltages. refer to table 27-13 located in section 27.1 ?dc characteristics?

1 ?. concurrently, the pwrt time-out (tpwrt) is applied before the internal reset is released. if tpwrt = 0 and a crystal oscillator is being used, then a nominal delay of tfscm = 100 is applied. the total delay in this case is tfscm. the bor status bit (rcon<1>) is set to indicate that a bor has occurred. the bor circuit continues to operate while in sleep or idle modes and resets the device should v dd fall below the bor threshold voltage. 24.4 watchdog timer (wdt) for dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices, the wdt is driven by the lprc oscillator. when the wdt is enabled, the clock source is also enabled. 24.4.1 prescaler/postscaler the nominal wdt clock source from lprc is 32.767 khz. this feeds a prescaler that can be config- ured for either 5-bit (divide-by-32) or 7-bit (divide-by- 128) operation. the prescaler is set by the wdtpre configuration bit. with a 32.767 khz input, the pres- caler yields a nominal wdt time-out period (t wdt ) of 1 ms in 5-bit mode, or 4 ms in 7-bit mode. a variable postscaler divides down the wdt prescaler output and allows for a wide range of time-out periods. the postscaler is controlled by the wdtpost<3:0> configuration bits (fwdt<3:0>) which allow the selection of 16 settings, from 1:1 to 1:32,768. using the prescaler and postscaler, time-out periods ranging from 1 ms to 131 seconds can be achieved. the wdt, prescaler and postscaler are reset: ? on any device reset ? on the completion of a clock switch, whether invoked by software (i.e., setting the oswen bit after changing the nosc bits) or by hardware (i.e., fail-safe clock monitor) ? when a pwrsav instruction is executed (i.e., sleep or idle mode is entered) ? when the device exits sleep or idle mode to resume normal operation ?by a clrwdt instruction during normal execution 24.4.2 sleep and idle modes if the wdt is enabled, it will continue to run during sleep or idle modes. when the wdt time-out occurs, the wdt will wake the device and code execution will continue from where the pwrsav instruction was executed. the corresponding sleep or idle bits (rcon<3:2>) will need to be cleared in software after the device wakes up. 24.4.3 enabling wdt the wdt is enabled or disabled by the fwdten configuration bit in the fwdt configuration register. when the fwdten configuration bit is set, the wdt is always enabled. the wdt can be optionally controlled in software when the fwdten configuration bit has been programmed to ? 0 ?. the wdt is enabled in software by setting the swdten control bit (rcon<5>). the swdten control bit is cleared on any device reset. the software wdt option allows the user application to enable the wdt for critical code segments and disable the wdt during non-critical segments for maximum power savings. the wdt flag bit, wdto (rcon<4>), is not automatically cleared following a wdt time-out. to detect subsequent wdt events, the flag must be cleared in software. note: the clrwdt and pwrsav instructions clear the prescaler and postscaler counts when executed. note: if the windis bit (fwdt<6>) is cleared, the clrwdt instruction should be executed by the application software only during the last 1/4 of the wdt period. this clrwdt window can be determined by using a timer. if a clrwdt instruction is executed before this window, a wdt reset occurs. dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 ds70591b-page 338 preliminary ?

word or byte-oriented operations ? bit-oriented operations ? literal operations ? dsp operations ? control operations table 25-1 shows the general symbols used in describing the instructions. the dspic33f instruction set summary in table 25-2 lists all the instructions, along with the status flags affected by each instruction. most word or byte-oriented w register instructions (including barrel shift instructions) have three operands: ? the first source operand, which is typically a register ?wb? without any address modifier ? the second source operand, which is typically a register ?ws? with or without an address modifier ? the destination of the result, which is typically a register ?wd? with or without an address modifier however, word or byte-oriented file register instructions have two operands: ? the file register specified by the value, ?f? ? the destination, which could be either the file register, ?f?, or the w0 register, which is denoted as ?wreg? most bit-oriented instructions (including simple rotate/shift instructions) have two operands: ? the w register (with or without an address modifier) or file register (specified by the value of ?ws? or ?f?) ? the bit in the w register or file register (specified by a literal value or indirectly by the contents of register ?wb?) the literal instructions that involve data movement can use some of the following operands: ? a literal value to be loaded into a w register or file register (specified by ?k?) ? the w register or file register where the literal value is to be loaded (specified by ?wb? or ?f?) however, literal instructions that involve arithmetic or logical operations use some of the following operands: ? the first source operand, which is a register ?wb? without any address modifier ? the second source operand, which is a literal value ? the destination of the result (only if not the same as the first source operand), which is typically a register ?wd? with or without an address modifier the mac class of dsp instructions can use some of the following operands: ? the accumulator (a or b) to be used (required operand) ? the w registers to be used as the two operands ? the x and y address space prefetch operations ? the x and y address space prefetch destinations ? the accumulator write-back destination the other dsp instructions do not involve any multiplication and can include: ? the accumulator to be used (required) ? the source or destination operand (designated as wso or wdo, respectively) with or without an address modifier ? the amount of shift specified by a w register, ?wn?, or a literal value the control instructions can use some of the following operands: ? a program memory address ? the mode of the table read and table write instructions note: this data sheet summarizes the features of the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?dspic33f/pic24h family reference manual?

2009 microchip technology inc. most instructions are a single word. certain double-word instructions are designed to provide all the required information in these 48 bits. in the second word, the 8 msbs are ? 0 ?s. if this second word is executed as an instruction (by itself), it will execute as a nop . the double-word instructions execute in two instruction cycles. most single-word instructions are executed in a single instruction cycle, unless a conditional test is true, or the program counter is changed as a result of the instruction. in these cases, the execution takes two instruction cycles with the additional instruction cycle(s) executed as a nop . notable exceptions are the bra (unconditional/computed branch), indirect call/goto , all table reads and writes and return/retfie instructions, which are single-word instructions but take two or three cycles. certain instructions that involve skipping over the subsequent instruction require either two or three cycles if the skip is performed, depending on whether the instruction being skipped is a single-word or two-word instruction. moreover, double-word moves require two cycles. note: for more details on the instruction set, refer to the ?16-bit mcu and dsc programmer?s reference manual?

dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices this appendix provides an overview of considerations for migrating from the dspic33fj06gs101/x02 and dspic33fj16gsx02/x04 family of devices to the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 family of devices. the code developed for the dspic33fj06gs101/x02 and dspic33fj16gsx02/x04 devices can be ported to the dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices after making the appropriate changes outlined below. a.1 device pins and peripheral pin select (pps) on dspic33fj06gs101/x02 and dspic33fj16gsx02/x04 devices, some peripherals such as the timer, input capture, output compare, uart, spi, external interrupts, analog comparator output, as well as the pwm4 pin pair, were mapped to physical pins via peripheral pin select (pps) functionality. on dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices, these peripherals are hard-coded to dedicated pins. because of this, as well as pinout differences between the two devices families, software must be updated to utilize peripherals on the desired pin locations. a.2 high-speed pwm a.2.1 fault and current-limit control signal source selection fault and current-limit control signal source selec- tion has changed between the two families of devices. on dspic33fj06gs101/x02 and dspic33fj16gsx02/x04 devices, fault1 through fault8 were assigned to fault and current-limit controls with the following values: ? 00000 = fault 1 ? 00001 = fault 2 ? 00010 = fault 3 ? 00011 = fault 4 ? 00100 = fault 5 ? 00101 = fault 6 ? 00110 = fault 7 ? 00111 = fault 8 on dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices, fault1 through fault8 were assigned to fault and current- limit controls with the following values: ? 01000 = fault 1 ? 01001 = fault 2 ? 01010 = fault 3 ? 01011 = fault 4 ? 01100 = fault 5 ? 01101 = fault 6 ? 01110 = fault 7 ? 01111 = fault 8 a.2.2 analog comparators connection connection of analog comparators to the pwm fault and current-limit control signal sources on dspic33fj06gs101/x02 and dspic33fj16gsx02/ x04 devices is performed by assigning a comparator to one of the fault sources via the virtual pps pins, and then selecting the desired fault as the source for fault and current-limit control. on dspic33fj32gs406/ 606/608/610 and dspic33fj64gs406/606/608/610 devices, analog comparators have a direct connection to fault and current-limit control, and can be selected with the following values for the clsrc or fltsrc bits: ? 00000 = analog comparator 1 ? 00001 = analog comparator 2 ? 00010 = analog comparator 3 ? 00011 = analog comparator 4 a.2.3 leading-edge blanking (leb) the leading-edge blanking delay (leb) bits have been moved from the lebcox register on dspic33fj06gs101/x02 and dspic33fj16gsx02/ x04 devices to the lebdlyx register on dspic33fj32gs406/606/608/610 and dspic33fj64gs406/606/608/610 devices. dspic33fj32gs406/606/608/610 and
