207 / 236 page  2016 Microchip Technology Inc. DS20005619A-page 207 MCP19124/5 RETFIE Return from Interrupt Syntax: [ label ] RETFIE Operands: None Operation: TOS PC, 1 GIE Status Affected: None Description: Return from Interrupt. Stack is POPed and Top-of-Stack (TOS) is loaded in the PC. Interrupts are enabled by setting Global Interrupt Enable bit, GIE (INTCON<7>). This is a two-cycle instruction. Words: 1 Cycles: 2 Example: RETFIE After Interrupt PC = TOS GIE = 1 RETLW Return with literal in W Syntax: [ label ] RETLW k Operands: 0 k 255 Operation: k (W); TOS PC Status Affected: None Description: The W register is loaded with the 8-bit literal ‘k’. The program counter is loaded from the Top-of-Stack (the return address). This is a two-cycle instruction. Words: 1 Cycles: 2 Example: TABLE DONE CALL TABLE;W contains ;table offset ;value GOTO DONE • • 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-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 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 Register f C |
