MAC Data Interface
The MAC Data Interface has two basic configurations as selected by the TBI configuration pin:
Modes of Operation
For the GMII configuration, the interface varies according to the speed of the link:
For the TBI Configuration, the interface is 10 bits x 125 MHz (supports 1000 only).
When no link is established (during auto-negotiation), clocks on the interface operate the same as
they do for the 10M MII mode.

GMII - supports 1000/100/10 links (TBI Configuration = Low)
TBI - supports 1000 only links (TBI Configuration = High)
1000 - GMII interface. 8 bits x 125 MHz
100 - MII interface. 4 bits x 25 MHz
10 - MII (4 bits x 2.5 MHz) or Serial (1bit x 10 MHz) as selected by the SER10 configuration
ball.
