Move f

[ label ] MOVF f,d

0 ≤ f ≤ 127

d ∈ [0,1]

(f) → (dest)

Z

00

1000 dfff ffff

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 ] OPTION

0000 0110 0010

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.

To maintain upward compatibil-

ity with future PICmicro®

products, do not use this

instruction.
