![### XOR Operation and Bit Toggling
**Question:**
7.2.4 - What bit positions (7 to 0) in R4 will be toggled when the following XOR operation is executed?
```
xor.b #01111110b, R4
```
**Options:**
- ☐ 0
- ☐ 1, 2, 3, 4, 5, and 6
- ☐ 7
- ☐ 0 and 7
**Explanation:**
The XOR operation (exclusive or) compares each bit of the contents of R4 with the corresponding bit of the given constant `01111110` (in binary). It sets the result bit to `1` if the bits being compared are different, and to `0` if they are the same.
Given the constant `01111110` (binary):
```
Bit positions: 7 6 5 4 3 2 1 0
Constant: 0 1 1 1 1 1 1 0
```
- The bit positions that have a `1` in the binary constant will be toggled in R4.
- In this case, bit positions 1 through 6 will be toggled.
Thus, the correct option is:
☐ 1, 2, 3, 4, 5, and 6](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8b5d3f26-cda5-43e5-8223-bfa02258241c%2F80313385-759c-4fe2-8c0b-57f3a31f5b97%2F9zbdsec_processed.png&w=3840&q=75)
