Software reset. Writing a 1 to this bit causes the EMAC logic to be reset. Software reset occurs
when the receive and transmit DMA controllers are in an idle state to avoid locking up the
Configuration bus. After writing a 1 to this bit, it may be polled to determine if the reset has
occurred. If a 1 is read, the reset has not yet occurred. If a 0 is read, then a reset has occurred.
0 A software reset has not occurred.
1 A software reset has occurred.
