OPTION
Load Option Register
Syntax:

OPTION
Operands:
None
Operation:
(W)
→ OPTION
Status Affected: None
Encoding:

0110
0010
Description:
The contents of the W register are
loaded in the OPTION register. This
instruction is supported for code
compatibility with PIC16C5X products.
Since OPTION is a readable/writable
register, the user can directly
address it.

Example
To maintain upward compatibility
with future PIC16CXX products, do
not use this instruction.
RETFIE
Return from Interrupt
Syntax:

Status Affected:
None
Encoding:

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:

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
=
