Software reset. Writing a one 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 one to this bit, it may be polled to determine if the reset has
occurred. If a one is read, the reset has not yet occurred. If a zero is read, then reset has occurred.
