Auxillary Carry #50

Auxillary Carry not working properly when INR, DCR, ADI is used

Hardik-Ahi commented 1 year ago

The CMP instruction too seems to be wrongly setting the auxiliary carry flag when it should not be set.

Consider the attached example program that converts a given decimal number to hexadecimal. Take the input value as '15', so the output should be '0F'. But it shows '35'.

Upon tracing, I found that for the operation (05 - 15) it is setting the auxiliary carry flag to 1, whereas it should be 0, because this operation does not require any borrow from the higher nibble.
