However,
for
compatibility with other Cirrus Logic
products, this pin should be connected
to the PCMCIA socket’s -INPACK pin.
CardBus Request: In CardBus mode,
this pin is the CREQ# signal.
Ready/Interrupt Request: In Memory 91
Card Interface mode, this input
indicates to the OZ6933 that the card is
either ready or busy. In I/O Card
Interface mode, this input indicates a
card interrupt request.
CardBus Interrupt: In CardBus mode,
this pin is the CINT# signal. This signal
is active-low and level-sensitive.

Card Enable pin is driven low by the 74
OZ6933 during card access cycles to
control byte/word card access. -CE1
enables even-numbered address bytes,
and -CE2 enables odd-numbered
address bytes. When configured for 8-
bit cards, only -CE1 is active and A0 is
used to indicate access of odd- or even-
numbered bytes.
