RETLW
Return with Literal in W
Syntax:
[

Operands:
0
≤
k
≤
255
Operation:
k

PC
Status Affected:
None
Encoding:

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
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

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.

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'.
