Program Operation

This operation is used to program data to the flash EEPROM and the option bits. Programming is

initiated when VPP reaches VCP (12.5V) level, CE is set to low, and OE is set to high.

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 = VIH, ALE = VIL, and PSEN = VIH.

2. VCP = 12V, VIH = VDD, VIL = Vss.

3. The program verify operation should follow the programming operaion.
