Load Option Register
[ label ]
None
(W) → OPTION
None
00
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. Using
only register instruction such as
MOVWF.

instruction.
Return from Interrupt
[ label ]
None
TOS → PC,
1 → GIE
None
00
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.
