DESCRIPTION
Input. This active high input enables the EEPROM to be read
or written by the LAN91C96I. Internally pulled up. Must be
connected to ground if no serial EEPROM is used.

nEN16
Input. When low the LAN91C96I is configured for 16 bit bus
operation. If left open the LAN91C96I works in 8 bit bus
mode. 16 bit configuration can also be programmed via serial
EEPROM or software initialization of the CONFIGURATION
REGISTER.
An external parallel resonance 20MHz crystal should be
connected across these pins. If an external clock source is
used, it should be connected to this pin (XTAL1) and XTAL2
should be left open.
An external parallel resonance 20MHz crystal should be
connected across these pins. If an external clock source is
used, it should be connected to XTAL1 and this pin (XTAL2)
should be left open.

INTERNAL ENDEC - (nXENDEC pin open). In this mode
TXP and TXN are the AUI transmit differential outputs. They
must be externally pulled up using 150 ohm resistors.
EXTERNAL ENDEC - (nXENDEC pin tied low). In this mode
the pins are inputs used for collision and carrier sense
functions.
AUI collision differential inputs. A collision is indicated by a
10MHz signal at this input pair.

INTERNAL ENDEC - 10BASE-T transmit differential outputs.
10BASE-T delayed transmit differential outputs. Used in
combination with TPETXP and TPETXN to generate the
10BASE-T transmit pre-distortion.

PWRDWN/
TXCLK
INTERNAL ENDEC - Powerdown input. It keeps the
LAN91C96I in powerdown mode when high (open). Must be
low for normal operation.
EXTERNAL ENDEC - Transmit clock input from external
ENDEC.
A resistor should be connected between this pin and analog
ground to determine the threshold level of the TP Receive,
AUI Receive, AUI Collision and AUI Transmit level.
When tied low the LAN91C96I is configured for EXTERNAL
ENDEC. When tied high or left open the LAN91C96I will use
its internal encoder/decoder.
