3 Figuring Out The Instruction Syntax The PIC instruction set is nice, in that once you figure out one instruction you ve figured out most of them, but it is a little different than what we re used to. The secret codes and how instructions are formed is described in the following tables: Byteoriented file register operations OPCODE d f (FILE #) TABLE 3: Field f W b OPCODE FIELD DESCRIPTIONS Descr iptio n Register file address (0x to 0x7F) Woring register (accumulator) Bit address within an 8bit file register Literal field, constant data or label x Don't care location (= 0 or ) The assembler will generate code with x = 0.It is the recommended form of use for compatibility with all Microchip software tools. d Destination select d = 0: store result in W, d = : store result in file register f. Default is d = PC TO PD Program Counter Timeout bit Powerdown bit d = 0 for destination W d = for destination f f = 7bit file register address Bitoriented file register operations OPCODE b (BIT #) f (FILE #) b = 3bit bit address f = 7bit file register address Literal and control operations General OPCODE (literal) = 8bit immediate value CALL and GOTO instructions only OPCODE (literal) = bit immediate value EE80L0P03
4 Comparing The Old And The New Let s loo at two equivalent programs. One on our old friend, the 80x86, the other on this newfangled PIC Microcontroller. Consider the following x86 program:.model small.data var db 33h var db 0A4h var3 db?.code.8086 start: mov mov Set data segment. ds, ax mov al, var Set Al to 33h mov bl, var Set BL to A4h add al, bl Compute al = al + bl mov var3, al Move sum to memory stop: jmp stop Stop program end start EE80L0P04
5 A Complete, But Simple PIC Program Our first PIC Processor Example include p6f877.inc Include file for register definitions ************************************************************ equates Ban0Ram equ 0x0 Equates mean the same as before! ************************************************************ variables Remember, these are in register file memory! cbloc Ban0Ram var 0x0 locations used for variables var 0x var3 0x temp location used for counter endc ************************************************************ start at the reset vector org 0x0 Set origin at memory address 0 nop very important required for debugger Start bcf STATUS,RP0 go to BANK 0 by setting bcf STATUS,RP RP:RP0 to 0 0. Initialize contents of variables. movlw 0x33 Move literal 33h into W. movwf var Move from W to var (initialize var) movlw 0A4h Move literal A4h into W. movwf var Move from W to var (initialize var) Do the addition. movf var,w Get data from var into W. addwf var,w Calculate W = var + var. movwf var3 Store result in var3. stop goto stop End EE80L0P05
6 The Hardest Thing About The PIC! The hardest thing to understand about the PIC is the conditional jump. There are only two jump instructions, but the way they wor is a little strange. Hang on! BTFSS Bit Test f, Sip if Set BTFSC Bit Test, Sip if Clear label label CY CY EE80L0P06
7 A Simple Decrement Loop On The PIC Our second PIC Processor Example include p6f877.inc Include file for register definitions ************************************************************ equates count equ 0x5 Manually assign register address! ************************************************************ start at the reset vector org 0x0 Set origin at memory address 0 nop very important required for debugger Start bcf STATUS,RP0 go to BANK 0 by setting bcf STATUS,RP RP:RP0 to 0 0. Initialize contents of variables. movlw 0x0A Initialize count to 0 decimal by movwf count setting W and moving W > count. Do the simple loop. loop decf count,f count = count. btfsc STATUS, Sip next instruction if = 0. stop goto stop End program. goto loop Continue looping! End EE80L0P07
