S32K144 FTM Input capture Duty 0 -100%

enzofarneti · ‎04-16-2020

Hi,

I have configured FTM0 in Dual Edge Capture Mode in order to read frequency and duty cycle of an input signal.

All works fine if the duty cycle of input signal is >0% and <100%.

I'd like to understand how I can read 0% and 100% of duty --> Input signal low or high DC.

Is it possible read input port also as GPIO (Digial Input) even this is configured as FTM0 port?

Best Regards
