PCI Mode (DEMUX connected to VSS):
LBI Address Bus
(GMODE.PERCFG=000
These pins provide the 16 bit Address bus for
the Local Bus Interface.
General Purpose Port
(GMODE.PERCFG=100
A general purpose 16-bit bi-directional parallel
port is provided on pins GP(15...0). Every pin
is individually programmable via register
GPDIR to operate as an output or an input.
If defined as output, the state of the pin is
directly controlled via the register GPDATA.
If defined as input, its current status can be
read via GPDATA. All changes may be
indicated via an interrupt vector. The
interrupts for each single pin can be masked
via mask register GPIM.
