103 / 148 page  2004 Microchip Technology Inc. Preliminary DS41211B-page 101 PIC12F683 RETLW Return with Literal in W Syntax: [ label ] RETLW k Operands: 0 ≤ k ≤ 255 Operation: k → (W); TOS → PC Status Affected: None Encoding: 11 01xx kkkk kkkk Description: The W register is loaded with the eight-bit literal ‘k’. The program counter is loaded from the top of the stack (the return address). This is a two-cycle instruction. Words: 1 Cycles: 2 Example: CALL TABLE;W contains table ;offset value • ;W now has table value • • ADDWF PC ;W = offset RETLW k1 ;Begin table RETLW k2 ; • • • RETLW kn ; End of table Before Instruction W= 0x07 After Instruction W= value of k8 RETURN Return from Subroutine Syntax: [ label ] RETURN Operands: None Operation: TOS → PC Status Affected: None Description: Return from subroutine. The stack is POPed and the top of the stack (TOS) is loaded into the program counter. This is a two-cycle instruction. 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 register ‘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 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 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’. Register f C Register f C |
