RETFIE
Return from Interrupt
Syntax:
[
label ] RETFIE
Operands:
None
Operation:
TOS
→ PC,
1
→ GIE
Status Affected:
None
Encoding:
00
0000
1001
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.

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
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:

Cycles:
2
Example
TABLE
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
Encoding:
00
0000

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'
.
