DAA operation in 8085 microprocessor
You cannot arrive at that condition from an addition of two valid BCD numbers. The largest possible LS nibbles are 9, so that means the largest possible LS result with a nibble carry is 2. So it's a moot point.
By the manual description it should leave a non-BCD result in the accumulator. An example of GIGO. A consequence of using the (very efficient) &quot;add 6&quot; algorithm on invalid data.
