Abstract
A system including an Ethernet transceiver PHY and a network device is disclosed. The Ethernet transceiver PHY includes register circuitry to store information associated with operating characteristics of the PHY. The network device couples to the Ethernet transceiver PHY in a closed system architecture and includes a system processor and an MDIO interface. The MDIO interface interacts with the PHY register circuitry during a normal operating mode. The system includes system interface circuitry to receive requests for accessing the register circuitry in a debug operating mode. The requests are generated external to the closed system architecture.
