EXAMPLE 1:
DS80456D-page 6
L0:daw.b
L1: ....
The Decimal Adjust instruction, DAW.b, may
improperly clear the Carry bit, C (SR<0>), when
executed.
Work around
Check the state of the Carry bit prior to executing
the DAW.b instruction. If the Carry bit is set, set the
Carry bit again after executing the DAW.b
instruction. Example 1 shows how the application
should process the Carry bit during a BCD addition
operation.
