#3429 - 16-bit BCD subtraction |
Hi and thank you for reading this!
I have to do a 16 bit subtraction with two BCD variables with a 80535 microcontroller. My problem is that the "DA A" instruction can´t be used for a subtraction. Maybe I have to build the 10´s complement of the variables first. Then an addition and "DA A" have to follow. |
