2.set PIO

2.1. set PIO as output high:
PioSetMapPins32Bank(PIO >>5 , (1UL << (PIO & 31)), (1UL << (PIO & 31)));
PioSetDir32Bank(PIO >>5, (1UL << (PIO & 31)), (1UL << (PIO & 31)));
PioSet32Bank(PIO >>5, (1UL << (PIO & 31)), 1UL << (PIO & 31)));
2.2. set PIO as output low:
PioSetMapPins32Bank(PIO >>5 , (1UL << (PIO & 31)), (1UL << (PIO & 31)));
PioSetDir32Bank(PIO >>5, (1UL << (PIO & 31)), (1UL << (PIO & 31)));
PioSet32Bank(PIO >>5, (1UL << (PIO & 31)), 0);

2.3. set PIO as input:
PioSetMapPins32Bank(PIO >>5 , (1UL << (PIO & 31)), (1UL << (PIO & 31)));
PioSetDir32Bank(PIO >>5, (1UL << (PIO & 31)), (0UL << (PIO & 31)));
