Output. NRZ Transmit Data for 10 Mbps
ENDEC interface.
Input. Carrier sense from 10 Mbps ENDEC
interface. This pin is ignored when MIISEL is
high.
Input. Collision detection indication from 10
Mbps ENDEC interface. This pin is ignored
when MIISEL is high.
Input. NRZ Receive Data from 10 Mbps ENDEC
interface. This pin is ignored when MIISEL is
high.
Input. 10 MHz transmit clock used in 10 Mbps
operation. This pin is ignored when MIISEL is
high.
Input. 10 MHz receive clock recovered by the 10
Mbps ENDEC. This pin is ignored when MIISEL
is high.
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.
