(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 setting
Global Interrupt Enable bit, GIE
(INTCON<7>). This is a two cycle
instruction.
