GPP I/O Signal Direction Control
Each bit of this bit field controls the direction (input/output) of the
corresponding General Purpose Pin. E.g. GPDIR bit 8 determins the I/O
characteristic of pin GP8.
Note: Even if not configured for GPP operation (bit field ’PERCFG’ in
GPDIR(i)=’0’ Pin GPi is configured as output pin.
GPDIR(i)=’1’ Pin GPi is configured as input pin.
register GMODE), this register must be programmed appropriately
for correct SSC or LBI operation.
(For detailed information refer to the chapters describing SSC and
LBI operation.)
