Block Guide — S12EETX4KV0 V00.04

1.Writing to an EEPROM address before initializing the ECLKDIV register.

2.Writing a byte or misaligned word to a valid EEPROM address.

3.Starting a command write sequence while a sector erase abort operation is active.

4.Writing to any EEPROM register other than ECMD after writing to an EEPROM address.

5.Writing a second command to the ECMD register in the same command write sequence.

6.Writing an invalid command to the ECMD register.

7.Writing to an EEPROM address after writing to the ECMD register.

8.Writing to any EEPROM register other than ESTAT (to clear CBEIF) after writing to the ECMD register.

9.Writing a “0” to the CBEIF flag in the ESTAT register to abort a command write sequence.

The ACCERR flag will not be set if any EEPROM register is read during a valid command write sequence.

The ACCERR flag will also be set if any of the following events occur:

1.Launching the sector erase abort command while a sector erase or sector modify operation is active which results in the early termination of the sector erase or sector modify operation (see section

4.1.3.5).

2.The MCU enters STOP mode and a command operation is in progress. The operation is aborted immediately and any pending command is purged (see section 4.3).

If the EEPROM memory is read during execution of an algorithm (CCIF = 0), the read operation will return invalid data and the ACCERR flag will not be set.

If the ACCERR flag is set in the ESTAT register, the user must clear the ACCERR flag before starting another command write sequence (see section 3.3.6).

The PVIOL flag will be set after the command is written to the ECMD register during a command write sequence if any of the following illegal operations are attempted, causing the command write sequence to immediately abort:

1.Writing the program command if the address written in the command write sequence was in a protected area of the EEPROM memory.

2.Writing the sector erase command if the address written in the command write sequence was in a protected area of the EEPROM memory.

3.Writing the mass erase command to the EEPROM memory while any EEPROM protection is enabled.

4.Writing the sector modify command if the address written in the command write sequence was in a protected area of the EEPROM memory.

If the PVIOL flag is set in the ESTAT register, the user must clear the PVIOL flag before starting another command write sequence (see section 3.3.6).
