1 Must be tied to ground.

2 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
