A little more information;

The following are examples of two binary to BCD conversions with the left
column
showing what the intermediate results should be and the right column showing
what the observed intermediate results were. (Leading additions of zeros
ignored.)
I haven't thought of a way to dig any deeper with my very limited debug
tools but my
first impression is that DAW isn't always generating a carry when I think it
should.

for 0x2FF
