10.2.3.7WRITE (Write Location)If erase/write operations are enabled in the EEPROM, this command will cause the contents of the EEPROM Data Register (E2P_DATA) to be written to the EEPROM location pointed to by the EPC_ADDRESS field of the EEPROM Command Register (E2P_CMD). The EPC_TIMEOUT bit of the EEPROM Command Register (E2P_CMD) is set if the EEPROM does not respond within 30mS.

10.2.3.8WRAL (Write All)If erase/write operations are enabled in the EEPROM, this command will cause the contents of the EEPROM Data Register (E2P_DATA) to be written to every EEPROM memory location. The EPC_TIMEOUT bit of the EEPROM Command Register (E2P_CMD) is set if the EEPROM does not respond within 30mS.
