DAW adjusts the eight-bit value in
WREG, resulting from the earlier
addition of two variables (each in
packed BCD format) and produces
a correct packed BCD result.

Decrement register 'f'. 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’ = 1, then the
bank will be selected as per the
BSR value (default).
