Revision 2.7 (03-15-10)
3.8.2.1
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.
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
page 90
for E2P_CMD field settings for each command.
