Aironet Wireless Communications, Inc. 4-4 Confidential and Proprietary
Notes:
CE1#, CE2#, IORD#, IOWR#, OE#, REG#, WAIT#, WE# - Input signals for bus control as defined
in the PCMCIA standard.
INPACK#, IOIS16#, STSCHG# - Output signals for bus control as defined in the PCMCIA standard.
RESET - Input signal for resetting the PC4500/4800. This signal must be asserted for a minimum of
20 microseconds.
IREQ# - Output signal that functions as the RDY/BSY line following the deassertion of the RESET
signal until the PC4500/4800 is configured and ready for operation. All access to the PC4500/4800
must be held off until this signal goes high. Once the reset operation is complete (interrupts are
enabled via the PCMCIA Configuration Options Register), this signal functions as a level-sensitive
interrupt to the host.
The WAIT# signal must be fully supported. A fixed number of wait states will not be sufficient for
the PC4500/4800 interface.

PCMCIA slot.
