1
Only on Rev C.2 silicon.
2
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.
3
Must be pulled down or left floating.
4
Must be pulled down or left floating. However, if compatibility with HiP4 silicon is required, this pin must be pulled up
or left floating.
