This pin is sampled at the end of RESET. When this
pin is sampled low the LAN91C96 is configured for
PCMCIA operation and all pin definitions correspond
to the PCMCIA mode. For LOCAL BUS operation this
pin is left open and it is used as a ROM chip select
output that goes active when nMEMR is low and the
address bus contains a valid ROM address. In
LOCAL BUS mode the LAN91C96 is pin compatible
with the LAN91C92 and LAN91C94. To enter the
68000 mode, this pin must be in the LOCAL BUS
mode at power up.
Input address lines 0 through 9.
LOCAL BUS - Input address line 10.
PCMCIA - Output. Flash Memory Write Enable used
for programming the attribute memory. Goes active
(low) when WE*=0 and COR2=1.
LOCAL BUS - Input address line 11.
PCMCIA - Output. Flash Memory Chip Select used to
access attribute memory. Goes active (low) when
nREG=0 nCE1=0 and A15=0.
Input address lines 12 through 18.
LOCAL BUS - Input address line 19.
PCMCIA - Card Enable 1 input. Used to select card on
even byte accesses.
LOCAL BUS - Address enable input. Used as an
address qualifier. Address decoding is only enabled
when AEN is low.
PCMCIA - Attribute memory and IO select input.
Asserted when the card attribute space or IO space is
being accessed.
68000 – Active low input. Address strobe.
LOCAL BUS - Byte High Enable input. Asserted (low)
by the system to indicate a data transfer on the upper
data byte.
PCMCIA - Card Enable 2 input. Used to select card on
odd byte accesses.
LOCAL BUS - Output. Optionally used by the
LAN91C96 to extend host cycles.
PCMCIA - Output. Optionally used by the LAN91C96
to extend host cycles.
