13.8.6
CPU Address:h605
Accessed by serial interface only (R/W)
Note: Before programming MII command: set FEN[6], check MIIC3, making sure no RDY and no VALID; then
program MII command.
13.8.7
CPU Address:h606
Accessed by serial interface only (R/W)
Note: Before programming MII command: set FEN[6], check MIIC3, making sure no RDY and no VALID; then
program MII command. Writing this register will initiate a serial management cycle to the MII management
interface.
