### 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.
