Set up the MII Mgmt for a write cycle to external the PHY AN Advertisement register (write the PHY address and
eTSEC Signals
Set source clock divide by 14, for example, to insure that EC_MDC clock speed is not greater than 2.5 MHz.
The AN Advertisement register is at offset address 0x04 from the external PHY address. (in this case 0x11)
