Subtract W from f

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