Freescale Semiconductor
Set up the MII Mgmt for a write cycle to external the PHY AN Advertisement register (write the PHY address and Register
eTSEC Signals
The AN Advertisement register is at offset address 0x04 from the external PHY address. (in this case 0x11)
TX_CLK
Write to MII Mgmt Control with 16-bit data intended for the external PHY AN Advertisement register,

Sum
set system clock divide by 14 for example to insure that MDC clock speed = 2.5 MHz
(Used to setup Reduced-Pin mode = 1, and TBIM = 0,statistics enable = 1)
Where u must be selected by the user for proper system configuration.
