If the MFP is programmed for SSC operation (bit field PERCFG=’011’ in register
GMODE), the lower 8 signal pins of the general purpose port (GPP) provide the SSC
specific signals whereas the upper 8 signal pins are still available for general purposes.
Nevertheless for SSC operation all GPP pins must be programmed for the appropriate
direction via register GPDIR.
