Function
Acts as GMII transmit data TXD0. Synchronous to the rising
edge of TXCLK. Internally Pull-up. User must add pull high
1K resister to 3.3V on 16 port application.

For two ADM6999U/UXs as 16port application :
Master: ADM6999U/UX will read 93C46/66 EEPROM first
Bank.(00
Slave0: ADM6999U/UX will read 93C66 EEPROM second
