Move f

1000 dfff ffff
The contents of register f is
moved to a destination dependant
upon the status of d. If d = 0, des-
tination is W register. If d = 1, the
destination is file register f itself. d
= 1 is useful to test a file register
since status flag Z is affected.

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.

To maintain upward compatibility
with future PICmicro™ products, do
not use this instruction.
