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.

TCK, TRST and PORESET have min VIH = 2.5V

VIL for IIC interface does not match IIC standard, but does meet IIC standard for VOL and should not cause any compatibility

issue.
