Subtract register ‘f’ and Carry flag
(borrow) from W (2’s complement
method). If ‘d’ is ‘0’, the result is
stored in W. If ‘d’ is ‘1’, the result is
stored 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).
