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.

Must be pulled down or left floating.

If PCI is not desired, this pin should be pulled up or left floating.

For information on how to use this pin, refer to
