ADM6926
Function Description
3.2
EEPROM Register Format
The EEPROM can be auto-detected by ADM6926 through the signature register. The
ADM6926 supports C66 EEPROM. After the EEPROM is loaded, the output pins of
ADM6926 are tri-state and released to CPU. The release time is about 30ms after end of
RESET. Whenever CPU modifies the setting of C66, the new value will be written to
ADM6926 at the same time. If CPU changes the port setting (Duplex/Speed/AEN), the
ADM6926 will restart the auto-negotiation automatically.
