SYSTEM AND METHOD FOR USING NETWORK INTERFACE CARD RESET PIN AS INDICATION OF LOCK LOSS OF A PHASE LOCKED LOOP AND BROWNOUT CONDITION

摘要

A method for providing an indication from a network interface controller to a microcontroller is disclosed wherein upon occurrence of a particular condition within the network interface controller, an indication is provided from a reset pin of the network interface controller to the microcontroller unit. Upon receipt of the indication by the microcontroller unit, communications between the network interface controller and the microcontroller unit are inhibited.
