(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: a value of 0.1 f (100 nf), 10v-20v is recommended. this capacitor should be a low equivalent series resistance (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 (pcb): 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 the pcb track inductance. note 1: this data sheet summarizes the features of the dspic33evxxxgm00x/10x 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 in the dspic33/pic24 family reference man- ual , 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, regardless of the adc voltage reference source. downloaded from: http:///

? 2013-2015 microchip technology inc. ds70005144d-page 21 dspic33evxxxgm00x/10x family 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 dspic33evxxxgm00x/10x family 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 sixteenth working register (w15) operates as a software stack pointer for interrupts and calls. in addition, the dspic33evxxxgm00x/10x devices include two alternate working register sets, which consist of w0 through w14. the alternate registers can be made persistent to help reduce the saving and restoring of register content during interrupt service routines (isrs). the alternate working registers can be assigned to a specific interrupt priority level (ipl1 through ipl6) by configuring the ctxtx<2:0> bits in the faltreg configuration register. the alternate working registers can also be accessed manually by using the ctxtswp instruction. the cctxi<2:0> and mctxi<2:0> bits in the ctxtstat register can be used to identify the current, and most recent, manually selected working register sets. 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 operates solely through the x memory agu, which accesses the entire memory map as one linear data space. on dspic33ev 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 (ds) memory map can optionally be mapped into program space (ps) 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. for more information on eds, psv and table accesses, refer to data memory (ds70595) and dspic33e/pic24e program memory (ds70000613) in the dspic33/ pic24 family reference manual . on dspic33ev 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. figure 3-1 illustrates the block diagram of the dspic33evxxxgm00x/10x family devices. 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 dspic33evxxxgm00x/10x family of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to cpu (ds70359) in 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. downloaded from: http:///

dspic33evxxxgm00x/10x family ds70005144d-page 30 ? 2013-2015 microchip technology inc. 3.7 arithmetic logic unit (alu) the dspic33evxxxgm00x/10x family alu is 16 bits wide and is capable of addition, subtraction, bit shifts and logic operations. unless otherwise mentioned, arithmetic operations are twos complement in nature. depending on the operation, the alu can affect the values of the carry (c), zero (z), negative (n), overflow (ov) and digit carry (dc) status bits in the sr register. the c and dc status bits operate as borrow and digit borrow bits, respectively, for subtraction operations. the alu can perform 8-bit or 16-bit operations, depending on the mode of the instruction that is used. the data for the alu operation can come from the w register array or from the data memory, depending on the addressing mode of the instruction. similarly, the output data from the alu can be written to the w register array or a data memory location. for information on the sr bits affected by each instruction, refer to the 16-bit mcu and dsc programmers reference manual (ds70157). 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. the 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 the single-cycle per bit of the 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 follows: 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:///

? 2013-2015 microchip technology inc. ds70005144d-page 35 dspic33evxxxgm00x/10x family 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 4-5 ). 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 the data memory space addressing and makes data in the program memory space accessible. 4.1.2 interrupt and trap vectors all dspic33evxxxgm00x/10x family 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. for more information on the interrupt vector tables, see section 7.1 interrupt vector table . figure 4-5: program memory organization 0 8 16 pc address 0x000000 0x000002 0x000004 0x000006 23 0000000000000000 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:///
dspic33evxxxgm00x/10x family ds70005144d-page 36 ? 2013-2015 microchip technology inc. 4.2 data address space the dspic33evxxxgm00x/10x family cpu has a separate, 16-bit wide data memory space. the data space (ds) is accessed using separate address gen- eration units (agus) for read and write operations. the data memory maps, which are presented by device family and memory size, are shown in figure 4-6 and figure 4-8 . all effective addresses (eas) in the data memory space are 16 bits wide and point to bytes within the ds. 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 (eds), which has a total address range of 16 mbytes. dspic33evxxxgm00x/10x family devices implement up to 20 kbytes of data memory (4 kbytes of data memory for special function registers and up to 16 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 ds 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 dspic33evxxxgm00x/10x family instruction set supports both word and byte operations. as a consequence of byte accessibility, all the 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 con- tains 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 reg- isters 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, there- fore, 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 dspic33evxxxgm00x/10x family 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 ds 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:///

? 2013-2015 microchip technology inc. ds70005144d-page 77 dspic33evxxxgm00x/10x family 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 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<3:0> 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 regis- ter 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. the operation of bit-reversed addressing is shown in figure 4-16 and tab l e 4 - 46 . 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:///

? 2013-2015 microchip technology inc. ds70005144d-page 81 dspic33evxxxgm00x/10x family 4.7.1 data access from program memory using table instructions the tblrdl and tblwtl instructions offer a direct method of reading or writing the lower word of any address within the program space without going through the data space. the tblrdh and tblwth instructions are the only method to read or write the upper 8 bits of a program space word as data. the pc is incremented by two for each successive 24-bit program word. this allows program memory addresses to directly map to data space addresses. program memory can thus be regarded as two 16-bit wide word address spaces, residing side by side, each with the same address range. the tblrdl and tblwtl instructions access the space that contains the least significant data word. tblrdh and tblwth access the space that contains the upper data byte. two table instructions are provided to move byte or word-sized (16-bit) data to and from program space. both function as either byte or word operations. 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. the phantom byte (d<15:8>) is always 0 . - in byte mode, this instruction maps the upper or lower byte of the program word to d<7:0> of the data address, as 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 application 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. accessing the program memory with table instructions is shown in figure 4-18 . figure 4-18: accessing program memory with table instructions 0 8 16 23 00000000 00000000 00000000 00000000 phantom byte tblrdh.b (wn<0> = 0 ) tblrdl.w tblrdl.b (wn<0> = 1 ) tblrdl.b (wn<0> = 0 ) 23 15 0 tblpag 02 0x000000 0x800000 0x020000 0x030000 program space the address for the table operation is determined by the data ea within the page defined by the tblpag register. only read operations are shown; write operations are also valid in the user memory area. downloaded from: http:///

? 2013-2015 microchip technology inc. ds70005144d-page 83 dspic33evxxxgm00x/10x family 5.0 flash program memory the dspic33evxxxgm00x/10x family devices contain internal flash program memory for storing and executing application code. the memory is readable, writable and erasable during normal operation over the entire v dd range. the flash memory can be programmed in the following three ways: in-circuit serial programming? (icsp?) run-time self-programming (rtsp) enhanced in-circuit serial programming (enhanced icsp) icsp allows for a dspic33evxxxgm00x/10x family device to be serially programmed while in the end application circuit. this is done with two lines for programming clock and programming data (pgecx/ pgedx) lines, 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. enhanced icsp uses an on-board bootloader, known as the program executive (pe), to manage the programming process. using an spi data frame format, the program executive can erase, program and verify program memory. for more information on enhanced icsp, refer to the specific device programming specification. rtsp is accomplished using the 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 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 the 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 the 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 dspic33evxxxgm00x/ 10x family of devices. it is not intended to be a comprehensive reference source. to complement the information in this data sheet, refer to flash pro- gramming (ds70609) in 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. 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:///
dspic33evxxxgm00x/10x family ds70005144d-page 84 ? 2013-2015 microchip technology inc. 5.2 rtsp operation rtsp allows the user application to erase a single page of memory, program a row and to program two instruction words at a time. see tab le 1 in the dspic33evxxxgm00x/10x product families section for the page sizes of each device. the flash program memory array is organized into rows of 64 instructions or 192 bytes. rtsp allows the user application to erase a page of program memory, which consists of eight rows (512 instructions) at a time, and to program one row or two adjacent words at a time. the 8-row erase pages and single row write rows are edge-aligned, from the beginning of program memory, on boundaries of 1536 bytes and 192 bytes, respectively. table 30-13 in section 30.0 electrical characteristics lists the typical erase and programming times. the basic sequence for rtsp word programming is to use the tblwtl and tblwth instructions to load two of the 24-bit instructions into the write latches found in configuration memory space. see figure 4-1 to figure 4-5 for write latch addresses. programming is performed by unlocking and setting the control bits in the nvmcon register. row programming is performed by loading 192 bytes into data memory and then loading the address of the first byte in that row into the nvmsrcadr register. once the write has been initiated, the device will auto- matically load the write latches and increment the nvmsrcadr and the nvmadr(u) registers until all bytes have been programmed. the rpdf bit (nvmcon<9>) selects the format of the stored data in ram to be either compressed or uncompressed. see figure 5-2 for data formatting. compressed data helps to reduce the amount of required ram by using the upper byte of the second word for the msb of the second instruction. for more information on erasing and programming the flash memory, refer to flash programming (ds70609) in the dspic33/pic24 family reference manual . figure 5-2: uncompressed/ compressed format 5.3 programming operations a complete programming sequence is necessary for programming or erasing the internal flash in rtsp mode. the processor stalls (waits) until the program- ming operation is finished. setting the wr bit (nvmcon<15>) starts the operation and the wr bit is automatically cleared when the operation is finished. 5.3.1 programming algorithm for flash program memory programmers can program two adjacent words (24 bits x 2) of program flash memory at a time on every other word address boundary (0x000002, 0x000006, 0x00000a, etc.). to do this, erase the page that contains the desired address of the location the user wants to change. 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 pro- gramming time until programming is complete. the two instructions following the start of the programming sequence should be nop s. refer to flash programming (ds70609) in the dspic33/pic24 family reference manual for details and code examples on programming using rtsp. note 1: before reprogramming either of the two words in a double-word pair, the user must erase the flash memory page in which it is located. 2: before reprogramming any word in a row, the user must erase the flash memory page in which it is located. lsw1 msb1 0x00 lsw2 0x00 msb2 lsw1 msb1 msb2 lsw2 15 7 0 15 7 0 even byte address even byte address increasing address increasing address uncompressed format (rpdf = 0 ) compressed format (rpdf = 1 ) downloaded from: http:///

dspic33evxxxgm00x/10x family ds70005144d-page 100 ? 2013-2015 microchip technology inc. 7.3 reset sequence a device reset is not a true exception because the interrupt controller is not involved in the reset process. the dspic33evxxxgm00x/10x family devices clear their registers in response to a reset, which forces the pc to zero. the device then begins program execution at location, 0x000000. a goto instruction at the reset address can redirect program execution to the appropriate start-up routine. 7.4 interrupt control and status registers dspic33evxxxgm00x/10x family devices implement the following registers for the interrupt controller: intcon1 intcon2 intcon3 intcon4 ifsx iecx ipcx inttreg 7.4.1 intcon1 through intcon4 global interrupt control functions are controlled from the intcon1, intcon2, intcon3 and intcon4 registers. intcon1 contains the interrupt nesting disable bit (nstdis), as well as the control and status flags for the processor trap sources. the intcon2 register controls external interrupt request signal behavior and also contains the global interrupt enable bit (gie). intcon3 contains the status flags for the dmt (dead- man timer), dma and do stack overflow status trap sources. the intcon4 register contains the ecc double-bit error (eccdbe) and software-generated hard trap (sght) status bit. 7.4.2 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 through software. 7.4.3 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. 7.4.4 ipcx the ipcx registers are used to set the interrupt priority level (ipl) for each source of interrupt. each user interrupt source can be assigned to one of eight priority levels. 7.4.5 inttreg the inttreg register contains the associated interrupt vector number and the new cpu interrupt priority level, which are latched into vector number (vecnum<7:0>) and interrupt priority level bit (ilr<3:0>) 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 as 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 in iec0<0> and the int0ip bits in the first position of ipc0 (ipc0<2:0>). 7.4.6 status/control registers although these registers are not specifically part of the interrupt control hardware, two of the cpu control registers contain bits that control interrupt functionality. for more information on these registers, refer to cpu (ds70359) in the dspic33/pic24 family reference manual . 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 software can change the current cpu interrupt priority level by writing to the iplx bits. the corcon register contains the ipl3 bit which, together with ipl<2:0>, also indicates the current cpu interrupt 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 7-3 to register 7-7 . note: any unimplemented or unused vector locations in the ivt should be pro- grammed with the address of a default interrupt handler routine that contains a reset instruction. downloaded from: http:///

dspic33evxxxgm00x/10x family ds70005144d-page 134 ? 2013-2015 microchip technology inc. 10.2.1 sleep mode the following events occur in sleep mode: the system clock source is shut down. if an on-chip oscillator is used, it is turned off. the device current consumption is reduced to a minimum, provided that no i/o pin is sourcing current. the fail-safe clock monitor does not operate, since the system clock source is disabled. the lprc clock continues to run in sleep mode if the wdt is enabled. the wdt, if enabled, is automatically cleared before entering sleep mode. some device features or peripherals can continue to operate. this includes items such as the input change notification (icn) on the i/o ports or peripherals that use an external clock input. any peripheral that requires the system clock source for its operation is disabled. the device wakes up from sleep mode on any of these events: any interrupt source that is individually enabled any form of device reset a wdt time-out on wake-up from sleep mode, the processor restarts with the same clock source that was active when sleep mode was entered. for optimal power savings, the internal regulator and the flash regulator can be configured to go into standby mode when sleep mode is entered by clearing the vregs (rcon<8>) and vregsf (rcon<11>) bits (default configuration). if the application requires a faster wake-up time, and can accept higher current requirements, the vregs (rcon<8>) and vregsf (rcon<11>) bits can be set to keep the internal regulator and the flash regulator active during sleep mode. 10.2.2 idle mode the following events 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 10.4 peripheral module disable ). if the wdt or fscm is enabled, the lprc also remains active. the device wakes 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 interrupt service routine (isr). all peripherals also have the option to discontinue operation when idle mode is entered to allow for increased power savings. this option is selectable in the control register of each peripheral; for example, the tsidl bit in the timer1 control register (t1con<13>). 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 either from sleep mode or idle mode. downloaded from: http:///
? 2013-2015 microchip technology inc. ds70005144d-page 135 dspic33evxxxgm00x/10x family 10.3 doze mode the preferred strategies for reducing power consump- tion 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 communi- cation 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 inter- rupt 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 pmdx 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 any effect and read values are invalid. a peripheral module is enabled only if both the associ- ated bit in the pmdx 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 pmdx register by default. note: if a pmdx bit is set, the corresponding module is disabled after a delay of one instruction cycle. similarly, if a pmdx 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:///

? 2013-2015 microchip technology inc. ds70005144d-page 143 dspic33evxxxgm00x/10x family 11.0 i/o ports many of the device pins are shared among the peripherals and the parallel i/o ports. all i/o input ports feature schmitt trigger inputs for improved noise immunity. all the pins in the device are 5v tolerant pins. 11.1 parallel i/o (pio) ports generally, a parallel i/o port that shares a pin with a peripheral is subservient to the peripheral. the peripherals output buffer data and control signals are provided to a pair of multiplexers. the multiplexers select whether the peripheral or the associated port has ownership of the output data and control signals of the i/o pin. the logic also prevents loop through, in which a ports digital output can drive the input of a peripheral that shares the same pin. figure 11-1 illustrates how ports are shared with other peripherals and the associated i/o pin to which they are connected. when a peripheral is enabled and the peripheral is actively driving an associated pin, the use of the pin as a general purpose output pin is disabled. the i/o pin can be read, but the output driver for the parallel port bit is disabled. if a peripheral is enabled, but the peripheral is not actively driving a pin, that pin can be driven by a port. all port pins have eight registers directly associated with their operation as digital i/o. the data direction register (trisx) determines whether the pin is an input or an output. if the data direction register bit is a 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 are disabled. this means that the corresponding latx and trisx registers, and the port pin are 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 output. figure 11-1: block diagram of a typical shared port structure note 1: this data sheet summarizes the features of the dspic33evxxxgm00x/10x family of devices. it is not intended to be a comprehensive reference source. to com- plement the information in this data sheet, refer to i/o ports (ds70000598) in the dspic33/pic24 family reference man- ual , 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. q d ck wr latx + trisx latch i/o pin wr portx data bus q d ck data latch read portx read trisx 10 1 0 wr trisx peripheral output data output enable peripheral input data i/o peripheral module peripheral output enable pio module output multiplexers output data input data peripheral module enable read latx downloaded from: http:///

? 2013-2015 microchip technology inc. ds70005144d-page 145 dspic33evxxxgm00x/10x family 11.4 slew rate selection the slew rate selection feature allows the device to have control over the slew rate selection on the required i/o pin which supports this feature. for this purpose, for each i/o port, there are two registers: sr1x and sr0x, which configure the selection of the slew rate. the register outputs are directly connected to the associated i/o pins, which support the slew rate selection function. the sr1x register specifies the msb and the sr0x register provides the lsb of the 2-bit field that selects the desired slew rate. for example, slew rate selections for porta are as follows: example 11-2: slew rate selections for porta 11.5 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 challenge 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. the peripheral pin select (pps) 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 par- ticular device, users can better tailor the device to their entire application, rather than trimming the application to fit the device. the pps configuration feature operates over a fixed subset of digital i/o pins. users may independently map the input and/or output of most digital peripherals to any one of these i/o pins. hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping after it has been established. 11.5.1 available pins the number of available pins is dependent on the par- ticular device and its pin count. pins that support the pps 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. 11.5.2 available peripherals the peripherals managed by the pps are all digital only peripherals. these include general serial commu- nications (uart and spi), general purpose timer clock inputs, timer related peripherals (input capture and output compare) and interrupt-on-change (ioc) inputs. in comparison, some digital only peripheral modules are never included in the pps feature, because the peripherals function requires special i/o circuitry on a specific port and cannot be easily connected to multiple pins. these modules include i 2 c and the pwm. a similar requirement excludes all modules with analog inputs, such as the adc converter. a key difference between the remappable and non- remappable peripherals is that the 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, the 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 the other digital i/o and digital communication peripherals associated with the pin. pri- ority is given regardless of the type of peripheral that is mapped. remappable peripherals never take priority over any analog functions associated with the pin. 11.5.3 controlling peripheral pin select the pps features are controlled through two sets of sfrs: one to map the peripheral inputs and the other to map the 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. 11.5.4 input mapping the inputs of th e pps options are mapped on the basis of the peripheral. that is, a control register associated with a peripheral dictates the pin it will be mapped to. the rpinrx registers are used to configure peripheral input mapping (see table 11-1 and register 11-1 through register 11-17 ). each register contains sets of 8-bit fields, with each set associated with one of the remap- pable peripherals. programming a given peripherals bit field with an appropriate 8-bit value maps the rpn pin with the corresponding value to that peripheral. for any given device, the valid range of values for any bit field corresponds to the maximum number of peripheral pin selects supported by the device. sr1ax, sr0ax = 00 = fastest slew rate sr1ax, sr0ax = 01 = 4x slower

dspic33evxxxgm00x/10x family ds70005144d-page 152 ? 2013-2015 microchip technology inc. 6. the pps pin mapping rules are as follows: only one output function can be active on a given pin at any time, regardless if it is a dedicated or remappable function (one pin, one output). it is possible to assign a remappable output function to multiple pins and externally short or tie them together for increased current drive. if any dedicated output function is enabled on a pin, it will take precedence over any remappable output function. if any dedicated digital (input or output) function is enabled on a pin, any number of input remappable functions can be mapped to the same pin. if any dedicated analog function(s) are enabled on a given pin, digital input(s) of any kind will all be disabled, although a single digital output, at the users cautionary dis- cretion, can be enabled and active as long as there is no signal contention with an external analog input signal. for example, it is possible for the adc to convert the digital output logic level, or to toggle a digital output on a comparator or adc input provided there is no external analog input, such as for a built-in self-test. any number of input remappable functions can be mapped to the same pin(s) at the same time, including to any pin with a single output from either a dedicated or remappable output. the trisx registers control only the digital i/o output buffer. any other dedicated or remappable active output will automatically override the trisx setting. the trisx regis- ter does not control the digital logic input buffer. remappable digital inputs do not automatically override trisx settings, which means that the trisx bit must be set to input for pins with only remappable input function(s) assigned all analog pins are enabled by default after any reset and the corresponding digital input buffer on the pin is disabled. only the analog pin select registers control the digital input buffer, not the trisx register. the user must disable the analog function on a pin using the analog pin select registers in order to use any digital input(s) on a corresponding pin; no exceptions. downloaded from: http:///

? 2013-2015 microchip technology inc. ds70005144d-page 199 dspic33evxxxgm00x/10x family 17.0 high-speed pwm module the dspic33evxxxgm00x/10x family devices support a dedicated pulse-width modulation (pwm) module with up to 6 outputs. the high-speed pwmx module consists of the following major features: three pwm generators two pwm outputs per pwm generator individual period and duty cycle for each pwm pair duty cycle, dead time, phase shift and frequency resolution of 8.32 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 three pwm generators. each pwm 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 adc 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 adc module based on the master time base. 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 input pin, that utilizes pps, can synchronize the high-speed pwmx module with an external signal. the synco1 pin is an output pin that provides a synchronous signal to an external device. figure 17-1 illustrates an architectural overview of the high-speed pwmx module and its interconnection with the cpu and other peripherals. 17.1 pwm faults the pwmx module incorporates multiple external fault inputs as follows: flt1 and flt2, available on 28-pin, 44-pin and 64-pin packages, which are remappable using the pps feature flt3, available on 44-pin and 64-pin packages, which is available as a fixed pin flt4-flt8, available on 64-pin packages, which are available as fixed pins flt32 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. 17.1.1 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 low externally or the internal pull-down resistor in the cnpdx register can be enabled . note 1: this data sheet summarizes the features of the dspic33evxxxgm00x/10x family of devices. it is not intended to be a comprehensive reference source. to com- plement the information in this data sheet, refer to high-speed pwm (ds70645) in 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: in edge-aligned pwm mode, the duty cycle, dead time, phase shift and frequency resolution are 8.32 ns at 60 mips. 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:///

(ds70353) in 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. downloaded from: http:///

dspic33evxxxgm00x/10x family ds70005144d-page 288 ? 2013-2015 microchip technology inc. 24.2 adc helpful tips 1. the smpix control bits in the adxcon2 registers: a) determine when the adc 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 adc analog scan channel list, defined in the adxcssl/adxcssh registers, starts over from the beginning. c) when the dma peripheral is not used (addmaen = 0 ), this determines when the adc 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 adc buffer used in this mode. the adc result buffer pointer to adc1buf0- adc1buff gets reset back to the beginning at adc1buf0. the dma address is incremented 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 adc has 16 result buffers. adc 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 adc buffer (adc1buf0-adc1buff) that the conversion results will be placed in. 3. when the dma module is enabled (addmaen = 1 ), the adc module has only 1 adc result buffer (i.e., adcxbuf0) per adc peripheral and the adc conversion result must be read, either by the cpu or dma controller, before the next adc 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 adc. 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 mux a selections use an0-an2. carefully study the adc block diagram to determine the configuration that will best suit your application. for configuration examples, refer to analog-to-digital converter (adc) (ds70621) in the dspic33/pic24 family reference manual . downloaded from: http:///

(icsp?) in-circuit emulation 27.1 configuration bits in dspic33evxxxgm00x/10x family 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 27-1 . 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 ensure that program 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 27-1 . note: this data sheet summarizes the features of the dspic33evxxxgm00x/10x 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:///

dspic33evxxxgm00x/10x family ds70005144d-page 328 ? 2013-2015 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 programmers reference manual (ds70157). table 28-1: symbols used in opcode descriptions field description #text means literal defined by text (text) means content of text [text] means the location addressed by text { } optional field or operation a ? {b, c, d} a is selected from the set of values b, c, d register bit field .b byte mode selection .d double-word mode selection .s shadow register select .w word mode selection (default) acc one of two accumulators {a, b} awb accumulator write-back destination address register ?? {w13, [w13]+ = 2} bit4 4-bit bit selection field (used in word-addressed instructions) ?? {0...15} c, dc, n, ov, z mcu status bits: carry, digit carry, negative, overflow, sticky zero expr absolute address, label or expression (resolved by the linker) f file register address ?? {0x0000...0x1fff} lit1 1-bit unsigned literal ?? {0,1} lit4 4-bit unsigned literal ?? {0...15} lit5 5-bit unsigned literal ?? {0...31} lit8 8-bit unsigned literal ?? {0...255} lit10 10-bit unsigned literal ?? {0...255} for byte mode, {0:1023} for word mode lit14 14-bit unsigned literal ?? {0...16384} lit16 16-bit unsigned literal ?? {0...65535} lit23 23-bit unsigned literal ?? {0...8388608}; lsb must be 0 none field does not require an entry, can be blank oa, ob, sa, sb dsp status bits: acca overflow, accb overflow, acca saturat e, accb saturate pc program counter slit10 10-bit signed literal ?? {-512...511} slit16 16-bit signed literal ?? {-32768...32767} slit6 6-bit signed literal ?? {-16...16} wb base w register ?? {w0...w15} wd destination w register ?? { wd, [wd], [wd++], [wd--], [++wd], [--wd] } wdo destination w register ?? { wnd, [wnd], [wnd++], [wnd--], [++wnd], [--wnd], [wnd+wb] } wm,wn dividend, divisor working r egister pair (direct addressing) downloaded from: http:///
