MOVF
Move f
Syntax:
[ label ]
MOVF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f)
→ (dest)
Status Affected:
Z
Description:
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:
0
≤ k ≤ 255
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.
