Description:
The W register is loaded with
the eight bit literal 'k'. The pro-
gram counter is loaded from the
top of the stack (the return
address). This is a two-cycle
instruction.

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

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.

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 reg-
ister 'f'.
