If [W<3:0> > 9] or [DC = 1 ], then
(W<3:0>) + 6 W<3:0>;
else
(W<3:0>) W<3:0>

DAW adjusts the 8-bit value in W,
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 W. If ‘d’ is ‘ 1 ’, the
result is stored back in register ‘f’.
If ‘a’ is ‘ 0 ’, the Access Bank is selected.
If ‘a’ is ‘ 1 ’, the BSR is used to select the
GPR bank.
If ‘a’ is ‘ 0 ’ and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f 95 (5Fh). See
Section 29.2.3 “Byte-Oriented and
Bit-Oriented Instructions in Indexed
Literal Offset Mode”
