When the contents of accumulator bits
0 thru 3 are greater than 9, or when
auxiliary carry (AC) is 1, 6 is added to
bits 0 thru 3. Bits 4 thru 7 are then
examined, and when bits 4thru 7
follwoing compensation of lower bits 0
thru 3 is greater than 9, or when carry
(C) is 1, 6 is added to bits 4 thru 7. As
a result, the cary flag can be set, but
cannot be cleared.
