MII-Enhanced Interrupt Event Feature
ThunderLAN can connect to an external PMI device through its industry stan-
dard MII interface. A full description of the MII can be found in the 802.3u stan-
dard. The ThunderLAN MII is enhanced in two ways:
-
The ThunderLAN MII can be shifted through software into a mode that
supports a connection to the TNETE211. The TNETE211 device provides
full 802.12 functionality and a 802.12 MII, which allows connection to a
PHY for 100VG-AnyLAN. The MII mode can be selected using the
MAC_Select field in the NetConfig register.

ThunderLAN’s MII passes interrupts from the attached PHY to the control-
ler. This enables the PHYs to interrupt the host only when needed.
