XC43 PWM Output voltage jumping from 6V to battery voltage randomly

I'm having an issue where the PWM outputs jump in voltage to battery voltage seemingly randomly and with no change in the displayed output on IQAN run. Anyone know what is going on?


What you are looking at is the effect of the leakage current.

If you are measuring on an output pin without any load connected, or with a load of relatively high impedance, you will see a voltage also when the output is off.
