FLTST - Facilitates the inclusion of packet forwarding information on the receive packet memory structure. When 0, RD0-
RD7 is always driven. When 1, RD0-RD7 is floated during RECEIVE FRAME STATUS WORD writes (RA2-RA16=0,
RCVDMA=1, nRWE0-nRWE3=0).
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.
