SPKROUT#
Digital audio signal which provides a single amplitude (digital)
audio waveform to drive the system's speaker. Passes through
SPKR# from an I/O PC Card. This signal must be held high
when no audio signal is present. Also, a resistor strapping input
during RESETDRV to determine the mapping of socket A and
socket B to one of four groups.
Power Control signal for card Vcc.
Power Control signal for card Vpp1
Power Control signal for card Vpp2

WAIT#
This signal is driven by the PC Card to delay completion of the
memory or I/O cycle in progress.
The host uses WE# for gating memory write data, and for
memory PC Cards that employ programmable memory.
Reflects the status of the Write Protect switch on some memory
PC Cards. If the memory PC Card has no write protect switch,
the card will connect this line to ground (the card can always be
written) or to Vcc (permanently write protected).

When the I/O interface is selected, this pin is used for the "I/O is
16-bit Port" function: asserted by the PC Card when the address
on the bus corresponds to an address to which the PC Card
responds, and the I/O Port which is addressed is capable of 16 bit
access. If this signal is not asserted during a 16-bit I/O access,
the system will generate 8-bit references to the even and odd byte
of the 16-bit port being accessed. If the 8-bit window size is
selected, the IOIS16# is ignored.
Zero Wait State. An active low output indicates that the PC Card
wishes to terminate the present bus cycle without inserting
additional wait states. This cycle will not be driven during a 16-
bit I/O access.
Socket A power signal for 3.3v or 5v
Socket B power signal for 3.3v or 5v
