(f)
(destination)
Z
The contents of register ‘f’ are
moved to a destination dependant
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.

The eight-bit literal ‘k’ is loaded
into W register. The “don’t cares”
will assemble as ‘

Description:
Subtract (2’s complement method)
W register from register ‘f’. If ‘d’ is

’, the result is stored in the W
register. If ‘d’ is ‘
1
’, the result is
stored back in register ‘f’.
