Consider two 8-bit registers A holding 0x5D and B holding 0xAF. Both patterns are treated as signed numbers. If the CPU performs A - B, would there be overflow, underflow, or neither? Justify. (See lecture slides for examples)
- **Step 1**: Compute A - B
- **Step 2**: The resulting pattern represents a ______ number.
- **Step 3**: A ______ 0 and B ______ 0. The expected result of A - B is ______.
