Load Option Register
[ label ]
None
(W)
None
00
The contents of the W register are
loaded in the OPTION register. This
instruction is supported for code
compatibility with PIC16C5X prod-
ucts. Since OPTION is a readable/
writable register, the user can
directly address it.

To maintain upward compatibil-
ity with future PICmicro
ucts, do not use this instruction.
Return from Interrupt
[ label ]
None
TOS
1
None
00
Return from Interrupt. Stack is
POPed and Top-of-Stack (TOS) is
loaded in the PC. Interrupts are
enabled by setting Global Inter-
rupt Enable bit, GIE
(INTCON<7>). This is a two-cycle
instruction.

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.
