? 2013-2014 microchip technology inc. ds70000689d-page 21 dspic33epxxxgm3xx/6xx/7xx 2.0 guidelines for getting started with 16-bit digital signal controllers 2.1 basic connection requirements getting started with the dspic33epxxxgm3xx/6xx/7xx family requires attention to a minimal set of device pin connections before proceeding with development. the following is a list of pin names, which must always be connected: all v dd and v ss pins (see section 2.2 decoupling capacitors ) all av dd and av ss pins (regardless if adc module is not used) (see section 2.2 decoupling capacitors ) v cap (see section 2.3 cpu logic filter capacitor connection (v cap ) ) 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 ) additionally, the following pins may be required: v ref +/v ref - pins are used when external voltage reference for adc module is implemented 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 to use ceramic capacitors. 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, above tens of mhz, add a second ceramic-type capacitor 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 dspic33epxxxgm3xx/6xx/7xx family of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the related section of the ?dspic33/pic24 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 available on all devices. refer to section 4.0 memory organization in this data sheet for device-specific register and bit information. note: the av dd and av ss pins must be connected independent of the adc voltage reference source. downloaded from: http:///

(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. for details, see 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 main oscillator guard ring guard trace oscillator pins downloaded from: http:///

? 2013-2014 microchip technology inc. ds70000689d-page 27 dspic33epxxxgm3xx/6xx/7xx 3.0 cpu the cpu has a 16-bit (data) modified harvard archi- tecture with an enhanced instruction set, including significant support for digital signal processing. the cpu has a 24-bit instruction word, with a variable length opcode field. the program counter (pc) is 23 bits wide and addresses up to 4m x 24 bits of user program memory space. an instruction prefetch mechanism helps maintain throughput and provides predictable execution. most instructions execute in a single-cycle, effective execu- tion rate, with the exception of instructions that change the program flow, the double-word move ( mov.d ) instruction, psv accesses and the table instructions. overhead-free program loop constructs are supported using the do and repeat instructions, both of which are interruptible at any point. 3.1 registers the dspic33epxxxgm3xx/6xx/7xx devices have sixteen 16-bit working registers in the programmers model. each of the working registers can act as a data, address or address offset register. the 16th working register (w15) operates as a software stack pointer for interrupts and calls. 3.2 instruction set the device instruction set has two classes of instruc- tions: the mcu class of instructions and the dsp class of instructions. these two instruction classes are seamlessly integrated into the architecture and exe- cute from a single execution unit. the instruction set includes many addressing modes and was designed for optimum c compiler efficiency. 3.3 data space addressing the base data space can be addressed as 4k words or 8 kbytes and is split into two blocks, referred to as x and y data memory. each memory block has its own independent address generation unit (agu). the mcu class of instructions operate solely through the x memory agu, which accesses the entire memory map as one linear data space. on dspic33ep devices, certain dsp instructions operate through the x and y agus to support dual operand reads, which splits the data address space into two parts. the x and y data space boundary is device-specific. the upper 32 kbytes of the data space memory map can optionally be mapped into program space at any 16k program word boundary. the program-to-data space mapping feature, known as program space visibility (psv), lets any instruction access program space as if it were data space. moreover, the base data space address is used in conjunction with a data space read or write page register (dsrpag or dswpag) to form an extended data space (eds) address. the eds can be addressed as 8m words or 16 mbytes. refer to data memory (ds70595) and program memory (ds70613) in the ?dspic33/ pic24 family reference manual? for more details on eds, psv and table accesses. on dspic33ep devices, overhead-free circular buffers (modulo addressing) are supported in both x and y address spaces. the modulo addressing removes the software boundary checking overhead for dsp algorithms. the x agu circular addressing can be used with any of the mcu class of instructions. the x agu also supports bit-reversed addressing to greatly simplify input or output data reordering for radix-2 fft algorithms. 3.4 addressing modes the cpu supports these addressing modes: inherent (no operand) relative literal memory direct register direct register indirect each instruction is associated with a predefined addressing mode group, depending upon its functional requirements. as many as six addressing modes are supported for each instruction. note 1: this data sheet summarizes the features of the dspic33epxxxgm3xx/6xx/7xx family of devices. it is not intended to be a comprehensive reference source. to com- plement the information in this data sheet, refer to the dspic33/pic24 family refer- ence manual , cpu (ds70359), which is available from the microchip web site ( www.microchip.com ). 2: some registers and associated bits described in this section may not be available on all devices. refer to section 4.0 memory organization in this data sheet for device-specific register and bit information. downloaded from: http:///

(ds70157) for information on the sr bits affected by each instruction. the core cpu incorporates hardware support for both multiplication and division. this includes a dedicated hardware multiplier and support hardware for 16-bit divisor division. 3.7.1 multiplier using the high-speed, 17-bit x 17-bit multiplier, 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 signed 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 3.7.2 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. 3.8 dsp engine the dsp engine consists of a high-speed, 17-bit x 17-bit multiplier, a 40-bit barrel shifter and a 40-bit adder/ subtracter (with two target accumulators, round and saturation logic). 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, unsigned or mixed-sign 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) table 3-2: dsp instructions summary instruction algebraic operation acc write back clr a = 0 yes ed a = (x C y) 2 no edac a = a + (x C y) 2 no mac a = a + (x y) yes mac a = a + x 2 no movsac no change in a yes mpy a = x y no mpy a = x 2 no mpy.n a = C x y no msc a = a C x y yes downloaded from: http:///

dspic33epxxxgm3xx/6xx/7xx ds70000689d-page 40 ? 2013-2014 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 ( figure 4-4 ). program memory addresses are always word-aligned on the lower word and addresses are incremented or decremented by two during 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 dspic33epxxxgm3xx/6xx/7xx devices reserve the addresses between 0x000000 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 address, 0x000000 of flash memory, with the actual address for the start of code at address, 0x000002 of flash memory. a more detailed discussion of the interrupt vector tables is provided in section 7.1 interrupt vector table . figure 4-4: program memory organization 0 8 16 pc address 0x000000 0x000002 0x000004 0x000006 23 00000000 00000000 00000000 00000000 program memory phantom byte (read as 0 ) least significant word most significant word instruction width 0x000001 0x000003 0x000005 0x000007 msw address (lsw address) downloaded from: http:///
? 2013-2014 microchip technology inc. ds70000689d-page 41 dspic33epxxxgm3xx/6xx/7xx 4.2 data address space the dspic33epxxxgm3xx/6xx/7xx cpu has a separate 16-bit wide data memory space. the data space is accessed using separate address generation units (agus) for read and write operations. the data memory maps, which are presented by device family and memory size, are shown in figure 4-5 through figure 4-7 . all effective addresses (eas) in the data memory space are 16 bits wide and point to bytes within the data space. this arrangement gives a base data space address range of 64 kbytes or 32k words. the base data space address is used in conjunction with a data space read or write page register (dsrpag or dswpag) to form an extended data space, which has a total address range of 16 mbytes. dspic33epxxxgm3xx/6xx/7xx devices implement up to 52 kbytes of data memory (4 kbytes of data memory for special function registers and up to 48 kbytes of data memory for ram). if an ea points to a location outside of this area, an all zero word or byte is 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 dspic33epxxxgm3xx/6xx/7xx instruction set supports both word and byte operations. as a consequence of byte accessibility, all effective address calculations are internally scaled to step through word-aligned memory. for example, the core recognizes that post-modified register indirect addressing mode [ws++] results in a value of ws + 1 for byte operations and ws + 2 for word operations. a data byte read, reads 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 lsb; the msb is not modified. a sign-extend ( se ) instruction 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 4 kbytes of the near data space, from 0x0000 to 0x0fff, is primarily occupied by special function registers (sfrs). these are used by the dspic33epxxxgm3xx/6xx/7xx 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 through a 13-bit abso- lute 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. downloaded from: http:///

? 2013-2014 microchip technology inc. ds70000689d-page 99 dspic33epxxxgm3xx/6xx/7xx 4.5.3 modulo addressing applicability modulo addressing can be applied to the effective address (ea) calculation associated with any w register. address boundaries check for addresses equal to: 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. 4.6 bit-reversed addressing bit-reversed addressing mode is intended to simplify data reordering 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. 4.6.1 bit-reversed addressing implementation bit-reversed addressing mode is enabled when all of these conditions are met: bwm bits (w register selection) in the modcon register are any value other than 1111 (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 addressing 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 does 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 addressing 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 can be enabled simultaneously using the same w register, but bit-reversed addressing operation will always take precedence for data writes when enabled. downloaded from: http:///

(icsp?) run-time self-programming (rtsp) icsp allows for a dspic33epxxxgm3xx/6xx/7xx 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: pgecx/pgedx), and three other lines for power (v dd ), ground (v ss ) and master clear (mclr ). this allows customers to manufacture boards with unprogrammed devices and then program the device 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 as a double program memory word, a row of 64 instructions (192 bytes), and erase program memory in blocks of 512 instruction words (1536 bytes) at a time. 5.1 table instructions and flash programming the flash memory read and the double-word programming operations make use of the tblrd and tblwt instructions, respectively. 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 addr ess in the program memory is formed using the tblpag<7:0> bits 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 dspic33epxxxgm3xx/6xx/7xx family of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the ?dspic33/pic24 family reference manual? , flash programming (ds70609), which is available from the microchip web site ( www.microchip.com ). 2: some registers and associated bits described in this section may not be available on all devices. refer to section 4.0 memory organization in this data sheet for device-specific register and bit information. 0 program counter 24 bits program counter tblpag reg 8 bits working reg ea 16 bits byte 24-bit ea 0 1/0 select using table instruction using user/configuration space select downloaded from: http:///

? 2013-2014 microchip technology inc. ds70000689d-page 155 dspic33epxxxgm3xx/6xx/7xx 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 cannot 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 configu- rations, 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 peripheral module disable the peripheral module disable (pmd) registers provide a method to disable a peripheral module by stopping all clock sources supplied to that module. when a peripheral is disabled, using the appropriate pmd control bit, the peripheral is in a minimum power consumption state. the control and status registers associated with the peripheral are also disabled, so writes to those registers do not have effect and read values are invalid. a peripheral module is enabled only if both the associated bit in the pmd register is cleared and the peripheral is supported by the specific dspic ? 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). downloaded from: http:///

? 2013-2014 microchip technology inc. ds70000689d-page 165 dspic33epxxxgm3xx/6xx/7xx 11.4 peripheral pin select (pps) a major challenge in general purpose devices is provid- ing the largest possible set of peripheral features while minimizing the conflict of features on i/o pins. the chal- lenge is even greater on low pin count devices. in an application where more than one peripheral needs to be assigned to a single pin, inconvenient work arounds in application code or a complete redesign may be the only option. peripheral pin select configuration provides an alternative to these choices by enabling peripheral set selection and their placement on a wide range of i/o pins. by increasing the pinout options available on a particular device, users can better tailor the device to their entire application, rather than trimming the application to fit the device. the peripheral pin select configuration feature oper- ates over a fixed subset of digital i/o pins. users may independently map the input and/or output of most dig- ital peripherals to any one of these i/o pins. hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping once it has been established. 11.4.1 available pins the number of available pins is dependent on the particular device and its pin count. pins that support the peripheral pin select feature include the designation, rpn or rpin, in their full pin designation, where n is the remappable pin number. rp is used to designate pins that support both remappable input and output functions, while rpi indicates pins that support remappable input functions only. 11.4.2 available peripherals the peripherals managed by the peripheral pin select are all digital only peripherals. these include general serial communications (uart and spi), general pur- pose timer clock inputs, timer-related peripherals (input capture and output compare) and interrupt-on-change inputs. in comparison, some digital only peripheral modules are never included in the peripheral pin select feature. this is because the peripherals function requires special i/o circuitry on a specific port and cannot be easily con- nected to multiple pins. these modules include i 2 c? and the pwm. a similar requirement excludes all modules with analog inputs, such as the a/d converter. a key difference between remappable and non- remappable peripherals is that remappable peripherals are not associated with a default i/o pin. the peripheral must always be assigned to a specific i/o pin before it can be used. in contrast, non-remappable peripherals are always available on a default pin, assuming that the peripheral is active and not conflicting with another peripheral. when a remappable peripheral is active on a given i/o pin, it takes priority over all other digital i/o and digital communication peripherals associated with the pin. priority is given regardless of the type of peripheral that is mapped. remappable peripherals never take priority over any analog functions associated with the pin. 11.4.3 controlling peripheral pin select peripheral pin select features are controlled through two sets of sfrs: one to map peripheral inputs and one to map outputs. because they are separately con- trolled, a particular peripherals input and output (if the peripheral has both) can be placed on any selectable function pin without constraint. the association of a peripheral to a peripheral-selectable pin is handled in two different ways, depending on whether an input or output is being mapped. downloaded from: http:///

? 2013-2014 microchip technology inc. ds70000689d-page 229 dspic33epxxxgm3xx/6xx/7xx 16.0 high-speed pwm module the dspic33epxxxgm3xx/6xx/7xx devices support a dedicated pulse-width modulation (pwm) module with up to 12 outputs. the high-speed pwmx module consists of the following major features: six pwm generators two pwm outputs per pwm generator individual period and duty cycle for each pwm pair duty cycle, dead time, phase shift and a frequency resolution of 7.14 ns independent fault and current-limit inputs for six pwm outputs redundant output center-aligned pwm mode output override control chop mode (also known as gated mode) special event trigger prescaler for input clock pwmxl and pwmxh output pin swapping independent pwm frequency, duty cycle and phase-shift changes for each pwm generator dead-time compensation enhanced leading-edge blanking (leb) functionality frequency resolution enhancement pwm capture functionality the high-speed pwmx module contains up to six pwm generators. each pwmx generator provides two pwm outputs: pwmxh and pwmxl . the master time base generator provides a synchronous signal as a common time base to synchronize the various pwm outputs. the individual pwm outputs are available on the output pins of the device. the input fault signals and current- limit signals, when enabled, can monitor and protect the system by placing the pwm outputs into a known safe state. each pwmx can generate a trigger to the adcx module to sample the analog signal at a specific instance during the pwm period. in addition, the high- speed pwmx module also generates a special event trigger to the adcx module, based on either of the two master time bases. the high-speed pwmx module can synchronize itself with an external signal or can act as a synchronizing source to any external device. the synci1 and synci2 input pins that utilize pps, can synchronize the high-speed pwmx module with an external signal. the synco1 and synco2 pins are output pins that provides a synchronous signal to an external device. figure 16-1 illustrates an architectural overview of the high-speed pwmx module and its interconnection with the cpu and other peripherals. 16.1 pwm faults the pwmx module incorporates multiple external fault inputs, which include flt1 and flt2. the inputs are remappable using the pps feature. flt3 is available on 44-pin, 64-pin and 100-pin packages; flt4 through flt8 are available on specific pins on 64-pin and 100-pin packages, and flt32, which has been implemented with class b safety features, and is available on a fixed pin on all devices. these faults provide a safe and reliable way to safely shut down the pwm outputs when the fault input is asserted. 16.1.1 pwm faults at reset during any reset event, the pwmx module maintains ownership of the class b fault, flt32. at reset, this fault is enabled in latched mode to ensure the fail-safe power-up of the application. the application software must clear the pwm fault before enabling the high- speed motor control pwmx module. to clear the fault condition, the flt32 pin must first be pulled high externally or the internal pull-up resistor in the cnpux register can be enabled. note 1: this data sheet summarizes the features of the dspic33epxxxgm3xx/6xx/7xx family of devices. it is not intended to be a comprehensive reference source. to com- plement the information in this data sheet, refer to the dspic33/pic24 family reference manual , high-speed pwm (ds70645), which is available from the microchip web site ( www.microchip.com ). 2: some registers and associated bits described in this section may not be available on all devices. refer to section 4.0 memory organization in this data sheet for device-specific register and bit information. note: in edge-aligned pwm mode, the duty cycle, dead time, phase shift and frequency resolution are 7.14 ns. note: the fault mode may be changed using the fltmod<1:0> bits (fclconx<1:0>), regardless of the state of flt32. downloaded from: http:///

? 2013-2014 microchip technology inc. ds70000689d-page 273 dspic33epxxxgm3xx/6xx/7xx 18.0 serial peripheral interface (spi) the spi module is a synchronous serial interface, useful for communicating with other peripheral or microcontroller devices. these peripheral devices can be serial eeproms, shift registers, display drivers, a/d converters, etc. the spi module is compatible with the motorola ? spi and siop interfaces. the dspic33epxxxgm3xx/6xx/7xx device family offers three spi modules on a single device. these modules, which are designated as spi1, spi2 and spi3, are functionally identical. each spi module includes an eight-word fifo buffer and allows dma bus connections. when using the spi module with dma, fifo operation can be disabled. the spi1 module uses dedicated pins which allow for a higher speed when using spi1. the spi2 and spi3 modules take advantage of the peripheral pin select (pps) feature to allow for greater flexibility in pin configuration of these modules, but results in a lower maximum speed. see section 33.0 electrical characteristics for more information. the spix serial interface consists of four pins, as follows: sdix: serial data input sdox: serial data output sckx: shift clock input or output ssx /fsyncx: active-low slave select or frame synchronization i/o pulse the spix module can be configured to operate with two, three or four pins. in 3-pin mode, ssx is not used. in 2-pin mode, neither sdox nor ssx is used. figure 18-1 illustrates the block diagram of the spix module in standard and enhanced modes. note 1: this data sheet summarizes the features of the dspic33epxxxgm3xx/6xx/7xx family of devices. it is not intended to be a comprehensive reference source. to com- plement the information in this data sheet, refer to the ?dspic33/pic24 family reference manual , serial peripheral interface (spi) (ds70005185), which is available from the microchip web site ( www.microchip.com ). 2: some registers and associated bits described in this section may not be available on all devices. refer to section 4.0 memory organization in this data sheet for device-specific register and bit information. note: in this section, the spi modules are referred to together as spix, or separately as spi1, spi2 and spi3. special function registers follow a similar notation. for example, spixcon refers to the control register for the spi1, spi2 and spi3 modules. downloaded from: http:///

dspic33epxxxgm3xx/6xx/7xx ds70000689d-page 330 ? 2013-2014 microchip technology inc. 23.2 adcx helpful tips 1. the smpix control bits in the adxcon2 registers: a) determine when the adcx interrupt flag is set and an interrupt is generated, if enabled. b) when the cscna bit in the adxcon2 reg- ister is set to 1 , this determines when the adcx analog scan channel list, defined in the ad1cssl/ad1cssh registers, starts over from the beginning. c) when the dma peripheral is not used (addmaen = 0 ), this determines when the adcx result buffer pointer to adc1buf0- adc1buff gets reset back to the beginning at adc1buf0. d) when the dma peripheral is used (addmaen = 1 ), this determines when the dma address pointer is incremented after a sample/conversion operation. adc1buf0 is the only adcx buffer used in this mode. the adcx result buffer pointer to adc1buf0- adc1buff gets reset back to the beginning at adc1buf0. the dma address is incre- mented after completion of every 32nd sample/conversion operation. conversion results are stored in the adc1buf0 register for transfer to ram using the dma peripheral. 2. when the dma module is disabled (addmaen = 0 ), the adcx has 16 result buffers. adcx conversion results are stored sequentially in adc1buf0-adc1buff, regardless of which analog inputs are being used subject to the smpix bits and the condition described in 1.c) above. there is no relationship between the anx input being measured and which adcx buffer (adc1buf0-adc1buff) that the conversion results will be placed in. 3. when the dma module is enabled (addmaen = 1 ), the adcx module has only 1 adcx result buffer (i.e., adc1buf0) per adcx peripheral and the adcx conversion result must be read, either by the cpu or dma controller, before the next adcx conversion is complete to avoid overwriting the previous value. 4. the done bit (adxcon1<0>) is only cleared at the start of each conversion and is set at the completion of the conversion, but remains set indefinitely, even through the next sample phase until the next conversion begins. if application code is monitoring the done bit in any kind of software loop, the user must consider this behavior because the cpu code execution is faster than the adcx. as a result, in manual sample mode, particularly where the users code is setting the samp bit (adxcon1<1>), the done bit should also be cleared by the user application just before setting the samp bit. 5. enabling op amps, comparator inputs and exter- nal voltage references can limit the availability of analog inputs (anx pins). for example, when op amp 2 is enabled, the pins for an0, an1 and an2 are used by the op amps inputs and output. this negates the usefulness of alternate input mode since the muxa selections use an0-an2. carefully study the adcx block diagram to deter- mine the configuration that will best suit your application. configuration examples are available in the ?dspic33/pic24 family reference manual? , analog-to-digital converter (adc) (ds70621) downloaded from: http:///

(icsp?) in-circuit emulation 30.1 configuration bits in dspic33epxxxgm3xx/6xx/7xx devices, the configuration bytes are implemented as volatile memory. this means that configuration data must be programmed each time the device is powered up. configuration data is stored at the top of the on-chip program memory space, known as the flash configu- ration bytes. their specific locations are shown in table 30-1 . the configuration data is automatically loaded from the flash configuration bytes to the proper configuration shadow registers during device resets. when creating applications for these devices, users should always specifically allocate the location of the flash configuration bytes for configuration data in their code for the compiler. this is to make certain that pro- gram code is not stored in this address when the code is compiled. the upper 2 bytes of all flash configuration words in program memory should always be 1111 1111 1111 1111 . this makes them appear to be nop instructions in the remote event that their locations are ever executed by accident. since config- uration bits are not implemented in the corresponding locations, writing 1 s to these locations has no effect on device operation. the configuration flash bytes map is shown in table 30-1 . note: this data sheet summarizes the features of the dspic33epxxxgm3xx/6xx/7xx family of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to the related section of the dspic33/pic24 family reference manual , which is available from the microchip web site ( www.microchip.com ). note: configuration data is reloaded on all types of device resets. note: performing a page erase operation on the last page of program memory clears the flash configuration bytes, enabling code protection as a result. therefore, users should avoid performing page erase operations on the last page of program memory. downloaded from: http:///

dspic33epxxxgm3xx/6xx/7xx ds70000689d-page 420 ? 2013-2014 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 8msbs are 0 s. if this second word is executed as an instruction (by itself), it executes 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, or a psv or table read is performed. in these cases, the execution takes multiple instruction cycles with the additional instruction cycle(s) executed as a nop . 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?
