Description

nIOIS16/

GPIO[57]

nPWAIT/

GPIO[56]

nPSKTSEL/

GPIO[54]

I/O Select 16. This signal is an input and is an acknowledge from the PCMCIA

ICOCZ card that the current address is a valid 16 bit wide I/O address.

See Note [1]

PCMCIA Wait. This signal is an input and is driven low by the PCMCIA card to

ICOCZ extend the length of the transfers to/from applications processor.

See Note [1]

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.
