### Hexadecimal Analysis Task

**Instruction:** Analyze the hexadecimal operation and determine the respective values for the accumulator, index register, memory locations, and status bits. Fill in the answers in the boxes provided.

**Given:**
- **4.6h A90A3F**

**Task:** Determine the four hexadecimal values after the operation executes, and identify the NZVC (Negative, Zero, Overflow, Carry) status bits.

1. **A: Accumulator**
   - Definition: Enter the 4-digit hexadecimal content of the accumulator.
   - Example: FFFF

2. **X: Index Register**
   - Definition: Enter the 4-digit hexadecimal content of the index register.
   - Example: 00F0

3. **0A3F: Contents of Memory Location 0A3F**
   - Enter the 4-digit hex number (Example: 1A23)

4. **0A41: Contents of Memory Location 0A41**
   - Enter the 4-digit hex number (Example: 1A23)

5. **NZVC: The Status Bits**
   - Enter the status using only 1s and 0s.
   - Example: 1100 
   - Format: Follow the format strictly (e.g., not 1 1 0 0 or 11xx)

**Response Fields:**

- _Accumulator:_ [               ]
- _Index Register:_ [               ]
- _Memory Location 0A3F:_ [               ]
- _Memory Location 0A41:_ [               ]
- _NZVC:_ [               ]

Make sure to enter all responses in hexadecimal format where applicable and use binary for NZVC. This exercise will aid in understanding memory operation and status indication in computer architecture.
