DESCRIPTION
202
Loopback
LBK
O4
Output. Active when LOOP bit is set (TCR bit 1).
Independent of port selection (MIISEL=X).
1
nLink
Status
nLNK
I with
pullup
Input. General purpose input port used to convey
LINK status (EPHSR bit 14). Independent of port
selection (MIISEL=X).
195
nFullstep
nFSTEP
O4
Output. Non volatile output pin. Driven by inverse
of FULLSTEP (CONFIG bit 10). Independent of
port selection (MIISEL=X).
6
MII Select
MIISEL
O4
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.
194
AUI Select
AUISEL
O4
Output. Non volatile output pin. Driven by AUI
SELECT (CONFIG bit 8). Independent of port
selection (MIISEL= X).
30
Transmit
Enable
100 Mbps
TXEN100
O12
Output to MII PHY.
Envelope to 100 Mbps
transmission. This pin stays low if MIISEL is low.
19
Carrier
Sense 100
Mbps
CRS100
I with
pulldown
Input from MII PHY. Envelope of packet reception
used for deferral and backoff purposes. This pin is
ignored when MIISEL is low.
12
Receive
Data Valid
RX_DV
I with
pulldown
Input from MII PHY.
Envelope of data valid
reception. Used for receive data framing. This pin
is ignored when MIISEL is low.
18
Collision
Detect 100
Mbps
COL100
I with
pulldown
Input from MII PHY. Collision detection input. This
pin is ignored when MIISEL is low.
25, 26, 28,
29
Transmit
Data
TXD0-
TXD3
O12
Outputs. Transmit Data nibble to MII PHY.
9
Transmit
Clock
TX25
I with
pullup
Input. Transmit clock input from MII. Nibble rate
clock (25 MHz). This pin is ignored when MIISEL
is low.
17
Receive
Clock
RX25
I with
pullup
Input. Receive clock input from MII PHY. Nibble
rate clock. This pin is ignored when MIISEL is low.
20, 21, 22,
24
Receive
Data
RXD0-
RXD3
I
Inputs.
Received Data nibble from MII PHY.
These pins are ignored when MIISEL is low.
198
Manage-
ment Data
Input
MDI
I with
pulldown
MII management data input.
196
Manage-
ment Data
Output
MDO
O4
MII management data output.
192
Manage-
ment Clock
MCLK
O4
MII management clock.
11
Receive
Error
RX_ER
I with
pulldown
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.
