130 / 182 page ![]() PIC16C925/926 DS39544A-page 128 Preliminary 2001 Microchip Technology Inc. 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 Q Cycle Activity: Q1 Q2 Q3 Q4 Decode Read register ’f’ Process data Write to destination Example RRF REG1,0 Before Instruction: REG1 = 1110 0110 C= 0 After Instruction: REG1 = 1110 0110 W= 0111 0011 C= 0 Register f C SLEEP 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. See Section 12.8 for more details. Words: 1 Cycles: 1 Q Cycle Activity: Q1 Q2 Q3 Q4 Decode No Operation No Operation Go to Sleep Example: SLEEP |
