RETURN Return from Subroutine Syntax: [ label ] RETURN Operands: None Operation: TOS → (PC) Status Affected: None Encoding: 00 0000 0000 1000 Description: Return from subroutine. The stack is popped and the Top of Stack (TOS) is loaded into the program counter. This is a two cycle instruction. Words: 1 Cycles: 2 Example RETURN After Interrupt PC = TOS RLF Rotate Left f through Carry Syntax: [ label ] RLF f,d Operands: 0 ≤ f ≤ 127 d ∈ [0,1] Operation: See description below Status Affected: C Encoding: 00 1101 dfff ffff Description: The contents of register 'f' are rotated one bit to the left through the Carry Flag. If 'd' is 0 the result is placed in the W register. If 'd' is 1 the result is stored back in reg- ister 'f'. Words: 1 Cycles: 1 Example RLF REG1,0 Before Instruction REG1 = 1110 0110 C= 0 After Instruction REG1 = 1110 0110 W= 1100 1100 C= 1 Register f C RRF Rotate Right f through Carry Syntax: [ label ] RRF f,d Operands: 0 ≤ f ≤ 127 d ∈ [0,1] Operation: See description below Status Affected: C Encoding: 00 1100 dfff ffff Description: The contents of register 'f' are rotated one bit to the right through the Carry Flag.If 'd' is 0 the result is placed in the W register. If 'd' is 1 the result is placed back in register 'f' . Words: 1 Cycles: 1 Example RRF REG1,0 Before Instruction REG1 = 1110 0110 C= 0 After Instruction REG1 = 1110 0110 W= 0111 0011 C= 1 SLEEP Go into Standby Mode Syntax: [ label ] SLEEP Operands: None Operation: 00h → WDT, 0 → WDT prescaler 1 → TO, 0 → PD Status Affected: TO, PD Encoding: 00 0000 0110 0011 Description: The power down status bit (PD) is cleared. Time-out status bit (TO) is set. Watchdog Timer and its prescaler are cleared. The processor is put into SLEEP mode with the oscillator stopped. Words: 1 Cycles: 1 Example: SLEEP Register f C |
