Note:
1. 0EH is for code memory programming . In lock bits programming, 0FH, 03H, 05H respect to lock bit 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.
