GPDAT[11..8]
GPDAT[11..8] Data
If GPIO[11..8] is configured for INPUT:
0 = GPDAT[11..8] indicates that the signal GPIO[11..8] is at a ‘low’ level
1 = GPDAT[11..8] indicates that the signal GPIO[11..8] is at a ‘high’ level
If GPIO[7..0] is conf igured for OUTPUT:
0 = GPDAT[11..8] indicates that the signal GPIO[11..8] is being driven ‘low’
1 = GPDAT[11..8] indicates that the signal GPIO[11..8] is being driven ‘high’
