1Must be tied to ground.
2Should be tied to VDDH via a 2K Ω external pull-up resistor.
3The default configuration of the CPM pins (PA[8–31], PB[18–31], PC[0–1,4–29], PD[7–25, 29–31]) is input. To prevent
excessive DC current, it is recommended either to pull unused pins to GND or VDDH, or to configure them as outputs.
4This pin is not connected. It should be left floating.
5Must be pulled down or left floating
