9.3.9.4. ERASE_NON_APPLICATION_ZONE
This command is used to erase the data in Non-Application Zones. The EEPROM memory is
organized into 16-bit words. Although erases are performed on single bit, the ERASE operation clears
an entire word in the memory. Therefore, performing an ERASE on any bit in the word will clear ALL
16 bits of that word to the state of ‘1’.
To erase Error Counter or the data in Application Zones, please refer to the following:
1. ERASE_APPLICATION_ZONE_WITH_ERASE command as specified in Section 9.3.9.5.
2. ERASE_APPLICATION_ZONE_WITH_WRITE_AND_ERASE command as specified in
Section 9.3.9.6.
3. VERIFY_SECURITY_CODE commands as specified in Section 9.3.9.7.
