**
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.

nBSELED/
RXD
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.
I with
EXTERNAL ENDEC - NRZ receive data input.

ENEEP
I with
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.
