ANMode
This field selects the way auto-negotiation advertisements are configured by
theTC9205M’s physical layer management polling entity and the way Phy speed
and duplex modes are extracted from management registers. It can enable
EEPROM forced modes that also use Duplex and Speed bits below to configure
the Phy mode.
00 – Normal Mode
01 – Advertise one mode
10 – Advertise multiple modes
11 – Disable auto-negotiation
Default is “00”(0).
ForceIntMode
This bit selects the source of internal port mode configuration. When this bit is ‘0’
the port's speed and duplex is configured according to Phy polling results,
otherwise it is set as indicated by following Speed and Duplex. Default is ‘0’.
