An autonomous drone uses an 8-bit register to store and sum consecutive altitude sensor readings. During a flight, the system attempts to perform the following addition of two 8-bit binary integers:
| 1 | 0 | 1 | 0 | 1 | 1 | 0 | 0 | ||
| 1 | 0 | 0 | 1 | 0 | 0 | 1 | 1 | + | |
| 1 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 |
Explain what has occurred as a result of this addition.
