DESCRIPTION
Output. Active when LOOP bit is set (TCR bit 1).
Independent of port selection (MIISEL=X).
Input. General purpose input port used to convey
LINK status (EPHSR bit 14). Independent of port
selection (MIISEL=X).
Output. Non volatile output pin. Driven by inverse
of FULLSTEP (CONFIG bit 10). Independent of
port selection (MIISEL=X).
Output. Non volatile output pin. Driven by MII
SELECT (CONFIG bit 15). High indicates the MII
port is selected, low indicates the 10 Mbps ENDEC
is selected.
Output. Non volatile output pin. Driven by AUI
SELECT (CONFIG bit 8). Independent of port
selection (MIISEL= X).
Output to MII PHY. Envelope to 100 Mbps
transmission. This pin stays low if MIISEL is low.

Input from MII PHY. Envelope of packet reception
used for deferral and backoff purposes. This pin is
ignored when MIISEL is low.
Input from MII PHY. Envelope of data valid
reception. Used for receive data framing. This pin
is ignored when MIISEL is low.
Input from MII PHY. Collision detection input. This
pin is ignored when MIISEL is low.

Input. Indicates a code error detected by PHY.
Used by the LAN91C100FD to discard the packet
being received. The error indication reported for
this event is the same as a bad CRC (Receive
Status Word bit 13). This pin is ignored when
MIISEL is low.
