ERASE (Erase Location): If erase/write operations are enabled in the EEPROM, this command will
erase the location selected by the EPC Address field (EPC_ADDR). The EPC_TO bit is set if the
EEPROM does not respond within 30ms.
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_TO bit is set if the EEPROM does not respond within
30ms.
