| Question 1 |
A single instruction to clear the lower four bits of the accumulator in 8085 assembly language?
| XRI OFH | |
| ANI FOH | |
| XRI FOH | |
| ANI OFH |
Question 1 Explanation:
Here, we use the AND as a accumulator with immediate. F leaves the high nibble whatever it is, 0 clears the lower nibble.
→ The XOR’s don’t reliably clear random bits and ANI OF clears the upper nibble, not the lower nibble.
→ The XOR’s don’t reliably clear random bits and ANI OF clears the upper nibble, not the lower nibble.
