Must be tied to ground.

Should be tied to VDDH via a 2K

Ω external pull-up resistor.

The 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.

This pin is not connected. It should be left floating.

Must be pulled down or left floating
