Transcribed Image Text:### Instruction for Completing the Hexadecimal and NZVC Values
**Problem Statement:**
For the given instruction `4.6a C90A3F`, determine the four hexadecimal values after executing the statement and identify the NZVC status bits.
**Components to Determine:**
1. **A: Accumulator**
- Enter the 4-digit hexadecimal content of the accumulator.
- Example format: `FFFF`
2. **X: Index Register**
- Enter the 4-digit hexadecimal content of the index register.
- Example format: `00F0`
3. **0A3F: Memory Location Content**
- Enter the 4-digit hexadecimal number for Memory Location `0A3F`.
- Example format: `1A34`
4. **0A41: Memory Location Content**
- Enter the 4-digit hexadecimal number for Memory Location `0A41`.
- Example format: `1A23`
5. **NZVC: Status Bits**
- Enter the status bits using only `1's` and `0's`.
- Example format: `1100` (Note: Do not enter as `1 1 0 0` or `11xx`)
**Enter Your Answers Below:**
- **Accumulator:**
- **Index Register:**
- **Memory Location 0A3F:**
- **Memory Location 0A41:**
- **NZVC Status Bits:**
### Explanation
- This exercise involves understanding and executing a machine language instruction where the outcome will affect the contents of registers and memory, and modify specific status flags represented by NZVC.
- Ensure your answers reflect correctly formatted hexadecimal values for registers and memory, and binary values for status flags.
