O4
NRZ transmit data output for 10 Mbps ENDEC
interface.
ID
Input. Carrier sense from 10 Mbps ENDEC
interface. This pin is ignored when MIISEL is
high.
ID
Input. Collision detection indication from 10
Mbps ENDEC interface. This pin is ignored
when MIISEL is high.
IP
NRZ receive data input from 10 Mbps ENDEC
interface. This pin is ignored when MIISEL is
high.
IP
Input. 10 MHz transmit clock used in 10 Mbps
operation. This pin is ignored when MIISEL is
high.
IP
Input. 10Mhz receive clock recovered by the
10 Mbps ENDEC. This pin is ignored when
MIISEL is high.
O4
Output. Active when LOOP bit is set (TCR bit
1). Independent of port selection (MIISEL=X).
