READ (Read Location): This command will cause a read of the EEPROM location pointed to by EPC
Address (EPC_ADDR). The result of the read is available in the E2P_DATA register.
WRITE (Write Location): If erase/write operations are enabled in the EEPROM, this command will
cause the contents of the E2P_DATA register to be written to the EEPROM location selected by the
EPC Address field (EPC_ADDR). The EPC_TO bit is set if the EEPROM does not respond within
30 ms.
WRAL (Write All): If erase/write operations are enabled in the EEPROM, this command will cause the
contents of the E2P_DATA register to be written to every EEPROM memory location. The EPC_TO
bit is set if the EEPROM does not respond within 30 ms.
