Register Description
Reserved.
Transmit Enable. When this bit is set, the Tx MAC is enabled to transmit frames. When reset, the
Tx MAC completes transmission of the packet currently being processed, then stops.
Receive Enable. When this bit is set, the Rx MAC is enabled to receive frames. When reset, the
Rx MAC completes reception of the packet currently being processed, then stops.
Flow-control Enable. When set, this enables the flow control functionality of the Tx MAC. This bit
should be set for the Tx MAC either to pause or to transmit a PAUSE frame.
Gigabit Enable. In Gigabit mode, this bit is always high and cannot be overwritten. In 10/100
mode, this bit is always low and cannot be overwritten.
