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.
