In the remote side, MII configuration for speed and duplex parameters in the digital
transceiver is automatic, according to the status of the SMI registers in the remote 10/
100Base-TX PHY as follows:
1. If the ANEGEN bit (bit 12) in the BMCR register of the 10/100Base-TX is asserted,
2. Otherwise, these parameters are derived from the SPEED (bit 13) and DUPLEX
In the local side, MII configuration for speed and duplex parameters in the digital
transceiver is automatic, according to the status of the local SMI registers as follows:
1. If the ANEGEN bit (bit 12) in the local BMCR register is asserted, then the speed and

In a MAC-MAC scenario, the MII speed and duplex parameters of the digital transceivers
at the ends are configured automatically according to the status of the attached 10/
100Base-TX PHY, as follows:
