(input) Driven low by the PCMCIA card to extend the
length of the transfers to/from the PXA255 processor.
PSKTSEL/GPIO[5
4]
ICOCZ
PCMCIA socket select.
(output) 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 the
address bus.
