(f) – (WREG) – (C)
N,OV, C, DC, Z
Subtract WREG and the carry flag
(borrow) from register 'f' (2’s com-
plement 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.
