Chapter 25 2 Kbyte EEPROM Module (S12XEETX2KV1)
25.4.2.2
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
sequence is as follows:
If a word to be programmed is in a protected area of the EEPROM memory, the PVIOL flag in the ESTAT
register will set and the program command will not launch. Once the program command has successfully
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.

1. Write to an EEPROM block address to start the command write sequence for the program
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. The data written will be programmed to the address written.
