Must be tied to ground.
Should be tied to VDDH via a 2K
Ω
external pull-up resistor.
3
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.
4
This pin is not connected. It should be left floating.
5
Must be pulled down or left floating
