Clause 40.4.6.1 of Standard 802.3 requires a PHY that is operating in 1000BASE-T mode to retrain if it detects

that its receiver status is not okay. Such a retrain prevents data from being transmitted or received for a long

period, but does not cause the LINK_STAT_LAT bit in the direct address map to latch low.

When B_1000_RTRN_EN is clear, 1000BASE-T retrain is disabled. In this case, when the receiver status

becomes not okay, it always results in the link dropping.

1: 1000BASE-T retrain is enabled.

0: 1000BASE-T retrain is disabled.

Base 10e Enable Register

Address: 0xB403, Reset: 0x0001, Name: B_10_E_EN

When set, this register enables 10BASE-Te operation. 10BASE-Te is a variant of 10BASE-T that transmits at a lower voltage level.
