Note:

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.
