Subtract W and the carry flag (bor-
row) 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 register '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).

The upper and lower nibbles of reg-
ister 'f' are exchanged. If 'd' is 0, the
result is placed in W. If 'd' is 1, the
result is placed in register '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).
