Program Command

The program operation will program a previously erased word in the EEPROM memory using an

embedded algorithm.

An example ﬂow to execute the program operation is shown in Figure 25-19. The program command write

sequence is as follows:

1. Write to an EEPROM block address to start the command write sequence for the program

command. The data written will be programmed to the address written.

2. Write the program command, 0x20, to the ECMD register.

3. Clear the CBEIF ﬂag in the ESTAT register by writing a 1 to CBEIF to launch the program

command.

If a word to be programmed is in a protected area of the EEPROM memory, the PVIOL ﬂag in the ESTAT

launched, the CCIF ﬂag in the ESTAT register will set after the program operation has completed unless a

new command write sequence has been buffered.
