DESCRIPTION
LOCAL BUS, PCMCIA - Input. Active low write strobe
used to access the LAN91C96 IO space.
68000 – Read/nWrite strobe to read from or write to
the chip.
LOCAL BUS - Active low signal used by the host
processor to read from the external ROM.
PCMCIA - Output Enable input used to read from the
COR, CSR and attribute memory.
Output. 4usec clock used to shift data in and out of a
serial EEPROM.
Output. Serial EEPROM chip select.
Output. Connected to the DI input of the serial
EEPROM.
Input. Connected to the DO output of the serial
EEPROM.
Input. External switches can be connected to these
lines to select between predefined EEPROM
configurations. The values of these pins are readable.

EXTERNAL ENDEC - Active low Transmit Enable
output.
INTERNAL ENDEC - Board Select LED activated by
accesses to I/O space (nIORD or nIOWR active with
AEN low and valid address decode for LOCAL BUS,
and with nREG low and COR0 high for PCMCIA). The
pulse is stretched beyond the access duration to make
the LED visible.
EXTERNAL ENDEC - NRZ receive data input.
INTERNAL ENDEC - Receive LED output.

Input. This active high input enables the EEPROM to
be read or written by the LAN91C96. Internally pulled
up. Must be connected to ground if no serial EEPROM
is used.
