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

None
Return from Interrupt. Stack is POPed
and Top of Stack (TOS) is loaded in
the PC. Interrupts are enabled by set-
ting Global Interrupt Enable bit, GIE
(INTCON<7>). This is a two cycle
instruction.
