SR
Start/Stop Receive
0: receive processor will enter stop state after the current
frame reception is completed. This value is effective only
when the receive processor is in the running or suspending
state. Note: In “Stop Receive” state, the PAUSE packet and
Remote Wake Up packet will not be affected and can be
received if the corresponding function is enabled.
1: receive processor will enter running state.

W* = only write when the transmit processor stopped.
W** = only write when the transmit and receive processor both stopped.
W*** = only write when the receive processor stopped.
