PWM pin usage

Other Parts Discussed in Thread: UCD90160

Hi Guys,

In UCD90160, PWM1/GPI1 means fixed 10-khz PWM output or GPI. Then is it output pin?

And excluding margining usage, could you please tell me below usage? Looks it is open-loop PWM.

Thanks a lot for your support.

Sincerely,

Jane

Hi there,

PWM1/GPI1 can be used as open loop PWM output or GPI input. So when you assign this pin as PWM, it outputs, and vice versa.

For your schematic, I believe you are using Pin31 as a GPI? Pushing button will trigger the GPI.

thanks

Luke

Hi Luke,

Many thanks. Originally I confused there is PWM outputs in pin functions for this pin. Now I am clear under you help.

Sincerely,
