31 / 130 page High-Performance Single-Chip 10/100 Ethernet Controller with HP Auto-MDIX Datasheet SMSC LAN9218 31 Revision 1.5 (07-18-06) DATASHEET The host can disable the EEPROM interface through the GPIO_CFG register. When the interface is disabled, the EEDIO and ECLK signals can be used as general-purpose outputs, or they may be used to monitor internal MII signals. 3.10.2.1 Supported EEPROM Operations The EEPROM controller supports the following EEPROM operations under host control via the E2P_CMD register. The operations are commonly supported by “93C46” EEPROM devices. A description and functional timing diagram is provided below for each operation. Please refer to the E2P_CMD register description in Section 5.3.23, "E2P_CMD – EEPROM Command Register," on page 90 for E2P_CMD field settings for each command. 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.
