Move f
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
(f) → (dest)
Z
The contents of register f is
moved to a destination dependent
upon the status of d. If d = 0,
destination 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.

Load Option Register
[ label ]
None
(W) → OPTION
None
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 read-
able/writable register, the user can
directly address it.
