System reset (active low).
10 ns max rise time. 1 ms min assertion time.
Toggles at 750 Hz nominal rate to indicate proper
operation. Period duration in excess of 200 ms
indicates hardware or software failure has occurred
and the interface should be reset. Note that
improper operation can also be indicated by short
pulses (<100 ns).
Asserts (active low) during initialization and when a
fault is detected or connection to the network is lost.
