Example:

Move f

[ label ] MOVF f,d

0 ≤ f ≤ 127

d ∈ [0,1]

(f) → (dest)

Z

00 1000 dfff ffff

The contents of register ‘f’ are

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.

Example:

Move Literal to W

[ label ] MOVLW k

0 ≤ k ≤ 255

k → (W)

None

11 00xx kkkk kkkk

The eight-bit literal ‘k’ is loaded

into the W register. The “don’t

cares” will assemble as ‘0’s.
