Freescale Semiconductor
This advertises to the Link Partner that the TBI supports PAUSE and Full Duplex mode and does not support Half Duplex mode
Set up the MII Mgmt for a write cycle to TBI’s AN Advertisement register (write the PHY address and Register address),
Set source clock divide by 14, for example, to insure that TSEC_MDC clock speed is not greater than 2.5 MHz.
Set up the MII Mgmt for a read cycle to TBI’s Control register (write the TBI’s address and Register address),
The AN Advertisement register is at offset address 0x04 from the TBI’s address. (in this case 0x10)

Write to MII Mgmt Control with 16-bit data intended for TBI’s AN Advertisement register,
Perform an MII Mgmt read cycle to verify state of TBI Control Register(0ptional)
(Uses the TBI address and Register address placed in MIIMADD register),
read the MIIMSTAT and look for AN Enable and other bit information.

This indicates that the eTSEC MII Mgmt bus is idle.
This indicates that the write cycle was completed.
Check to see if MII Mgmt write is complete.
(This example has Statistics Enable = 1)
Perform an MII Mgmt write cycle to TBI.
Assign a Physical address to the TBI,
Setup the MII Mgmt clock speed,
