PRODUCTION DATA
MII Loopback is the shallowest loop through the PHY. It is a useful test mode to validate communications between the MAC and the PHY. When in MII Loopback, data transmitted from a connected MAC on the TX path is internally looped back in the DP83TD510E to the RX pins where it can be checked by the MAC.
