Set up the MII Mgmt for a write cycle to the external PHY Control register (write the PHY address and Register address),
This enables the external PHY to restart Auto-Negotiations using the configuration set in the AN Advertisement register.
Other information about the link is also returned. (Extend Status, No pre, Remote Fault, An Ability, Link status, extend
Set up the MII Mgmt for a read cycle to the PHY MII Mgmt register (write the PHY address and Register address),
Setting up the MII Mgmt for a write cycle to TBI MII Mgmt register (write the TBI’s address and Register address),
read the MII Mgmt AN Link Partner Base Page Ability register and check bits 9 and 10. (Half and Full Duplex)
Writing to MII Mgmt Control with 16-bit data intended for TBI’s MII Mgmt control register (TBI control),
MII Mgmt AN Link Partner Base Page Ability ---> [0000_0000_0000_0000_0000_000x_x110_0000]
The Control register is at offset address 0x00 from the external PHY address. (in this case 0x11)
read the MII Mgmt AN Expansion register and check bits 13 and 14. (NP Able and Page Rx’d)

Perform an MII Mgmt read cycle of AN Link Partner Base Page Ability Register. (Optional)
Write to MII Mgmt Control with 16-bit data intended for the external PHY Control register,
(Uses the PHY address (0x11) and Register address (6) placed in MIIMADD register)
(Uses the PHY address (0x11) and Register address (5) placed in MIIMADD register)
The PHY Status register is at address 0x1 and in this case the PHY Address is 0x2.
(Uses the PHY address (2) and Register address (1) placed in MIIMADD register)
