Bank 3 - Management Interface
Bank 3 - Revision Register
MSK_CRS100 - Disables CRS100 detection during transmit in half duplex mode (SWFDUP=0).
MDO - MII Management output. The value of this bit drives the MDO pin.
MDI - MII Management input. The value of the MDI pin is readable using this bit.
MDCLK - MII Management clock. The value of this bit drives the MDCLK pin.
MDOE - MII Management output enable. When high pin MDO is driven, when low pin MDO is tri-
stated.
The purpose of this interface, along with the corresponding pins is to implement MII PHY management
in software.
CHIP - Chip ID. Can be used by software drivers to identify the device used.
REV - Revision ID. Incremented for each revision of a given device.
