nIOIS16/
GPIO[57]
ICOCZ
I/O Select 16. This signal is an input and is an acknowledge from the PCMCIA
card that the current address is a valid 16 bit wide I/O address.
See Note [1]
nPWAIT/
GPIO[56]
ICOCZ
PCMCIA Wait. This signal is an input and is driven low by the PCMCIA card to
extend the length of the transfers to/from applications processor.
See Note [1]
nPSKTSEL/
GPIO[54]
ICOCZ
PCMCIA Socket Select. This signal is an output and is used by external steering
logic to route control, address and data signals to one of the two PCMCIA
sockets. When PSKTSEL is low, socket zero is selected. When PSKTSEL is high,
socket one is selected. This signal has the same timing as an address.
See Note [1]
nPREG/
GPIO[55]
ICOCZ
PCMCIA Register Select. This signal is an output and indicates that, on a memory
transaction, the target address is attribute space. This signal has the same timing
as address.
See Note [1]
