Program Operation
This operation is used to program data to the flash EEPROM and the option bits. Programming is
initiated when V
Program Verify Operation
All data must be checked after programming. This operation should be performed after each byte is
programmed, and it will ensure a substantial program margin.
Notes:
1. During all of these operations, RST = V
2. V
3. The program verify operation should follow the programming operaion.
ABSOLUTE MAXIMUM RATINGS
