How do you make an eTPU output low using KNOCK?

Question asked by Andrei Chichak on Dec 11, 2018

The KNOCK function generates pulses at a particular rotational angle given a start angle and width angle.

 

We are using the KNOCK function off label and occasionally don't need it to be active. I would like the pin to be low and stay low.

 

By setting the start and width to 0, KNOCK generates a runt pulse which triggers our circuit.

By setting the width to 0 and the start != 0, KNOCK makes the pin go high continually.

If I call fs_etpu_disable, the pin goes high continually.

 

Using the KNOCK function, how would I set the pin low continually?

 

Thanks,

Andrei
