Description:

Words:

Cycles:

Example:

Move f

[ label ] MOVF f,d

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.

MOVLW

Move literal to W

Syntax:

[ label ] MOVLW k

Operands:

Operation:

k → (W)

Status Affected: None

Description:

The eight-bit literal ‘k’ is loaded into

W register. The “don’t cares” will

assemble as ‘0’s.
