#156237 - check for zero code options? |
I am putting #01H into the accumulator and rotating it left through the carry but right where that ">" is I am checking another register to see if it has a zero value. I can't load it into the ACC and test it for zero. What else can I load it into to test for zero (JZ) without affecting the value in the ACC?
