1
The default configuration of the CPM pins (PA[0–31], PB[4–31], PC[0–31], PD[4–31]) is input. To prevent excessive
DC current, it is recommended to either pull unused pins to GND or VDDH, or to configure them as outputs.
2
Must be pulled down or left floating.
3
If PCI is not desired, this pin should be pulled up or left floating.
