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.
