DS30561B-page 75 PIC12C67X CLRWDT Clear Watchdog Timer Syntax: [ label ] CLRWDT Operands: None Operation: 00h → WDT 0 → WDT prescaler, 1 → TO 1 → PD Status Affected: TO, PD Encoding: 00 0000 0110 0100 Description: CLRWDT instruction resets the Watchdog Timer. It also resets the prescaler of the WDT. Status bits TO and PD are set. Words: 1 Cycles: 1 Example CLRWDT Before Instruction WDT counter = ? After Instruction WDT counter = 0x00 WDT prescaler= 0 TO =1 PD =1 COMF Complement f Syntax: [ label ] COMF f,d Operands: 0 ≤ f ≤ 127 d ∈ [0,1] Operation: (f) → (dest) Status Affected: Z Encoding: 00 1001 dfff ffff Description: The contents of register ’f’ are complemented. If ’d’ is 0, the result is stored in W. If ’d’ is 1, the result is stored back in register ’f’. Words: 1 Cycles: 1 Example COMF REG1,0 Before Instruction REG1 = 0x13 After Instruction REG1 = 0x13 W= 0xEC DECF Decrement f Syntax: [ label ] DECF f,d Operands: 0 ≤ f ≤ 127 d ∈ [0,1] Operation: (f) - 1 → (dest) Status Affected: Z Encoding: 00 0011 dfff ffff Description: Decrement register ’f’. If ’d’ is 0, the result is stored in the W regis- ter. If ’d’ is 1, the result is stored back in register ’f’. Words: 1 Cycles: 1 Example DECF CNT, 1 Before Instruction CNT = 0x01 Z= 0 After Instruction CNT = 0x00 Z= 1 DECFSZ Decrement f, Skip if 0 Syntax: [ label ] DECFSZ f,d Operands: 0 ≤ f ≤ 127 d ∈ [0,1] Operation: (f) - 1 → (dest); skip if result = 0 Status Affected: None Encoding: 00 1011 dfff ffff Description: The contents of register ’f’ are decremented. If ’d’ is 0, the result is placed in the W register. If ’d’ is 1, the result is placed back in reg- ister ’f’. If the result is 0, the next instruc- tion, which is already fetched, is discarded. A NOP is executed instead making it a two cycle instruction. Words: 1 Cycles: 1(2) Example HERE DECFSZ CNT, 1 GOTO LOOP CONTINUE • • • Before Instruction PC = address HERE After Instruction CNT = CNT - 1 if CNT = 0, PC = address CONTINUE if CNT ≠ 0, PC = address HERE+1 |
