(f) – (WREG)
N,OV, C, DC, Z
Subtract WREG from register 'f'
(2’s complement method). If 'd' is
0, the result is stored in WREG. If
'd' is 1, the result is stored back in
register 'f' (default). If ’a’ is 0, the
Access Bank will be selected,
overriding the BSR value. If ’a’ is
1, the Bank will be selected as per
the BSR value.
