1. 0EH is for code memory programming. In lock bits programming, 0FH, 03H, 05H, respect to lock bits
1, 2, 3.
2. 0CH is for code memory verification and 0DH is for concurrent memory verification. 09H is for Lock
bits verification.
3. Address don’t care while lock bits’ programming or verification.
4. Data don’t care while lock bits’ programming.
