MOVF
Move f
Syntax:
[ label ]
MOVF f,d
0 ≤ f ≤ 127
Operands:
d ∈ [0,1]
(f) → (dest)
Operation:
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.

Example:
MOVF
FSR, 0
After Instruction

MOVLW
Move literal to W
Syntax:
[ label ]
MOVLW k
0 ≤ k ≤ 255
Operands:
k → (W)
Operation:
Status Affected: None
Description:
The eight-bit literal ‘k’ is loaded into
W register. The “don’t cares” will
assemble as ‘0’s.
Words:

Example:
MOVLW
0x5A
After Instruction
