ERAL (Erase All)
If erase/write operations are enabled in the EEPROM, this command will initiate a bulk erase of the
entire EEPROM. The EPC_TIMEOUT bit of the
EEPROM does not respond within 30mS.
EWDS (Erase/Write Disable)
After this command is issued, the EEPROM will ignore erase and write commands. To re-enable
erase/write operations, the EWEN command must be issued.
