General Purpose I/O
6.3
The PCI 9030 supports nine general purpose input
and output pins, multiplexed GPIO0/WAITo#, GPIO1/
LLOCKo#, GPIO2/CS2#, GPIO3/CS3#, GPIO4/LA27,
GPIO5/LA26, GPIO6/LA25, and GPIO7/LA24, and
GPIO8. The PCI 9030 default condition is the General
Purpose Input for GPIO[3:0], with Local Address
LA[27:24] for GPIO[4:7], and General Purpose Input
for GPIO8. The general purpose I/O pins and
functionality can be enabled and selected in the
General Purpose I/O Control register (GPIOC[31:0]).

GENERAL PURPOSE I/O
GPIO[8:0] pins configured as inputs (GPIO[8, 3:0] are
inputs with the default GPIOC register value) are
active regardless of whether the PCI 9030 owns the
Local Bus.
GPIO[8:0] pins configured as outputs are driven only
when the PCI 9030 owns the Local Bus. (Refer to
PCI 9030 Errata #2.)
It is recommended that unused GPIO pins be
configured as outputs, rather than inputs (by default,
GPIO[8, 3:0] are inputs); otherwise, input pins should
be pulled to a known state.
