Clip output to CPU interface

Post by dslocum » Fri Mar 03, 2017 5:58 am

I'm interfacing a CPU with a LCD to the FV1. I would like to use the CLIP output pin into a CPU input - maybe an interrupt on change input so that the LCD displays the clip event rather than a hardware LED.

Is the CLIP output a standard open drain output? Should I pull up with something like a 10K? Any other gotchas?

Thanks

I believe it is a standard output pad that goes low when the signal clips, I do not believe you need a pull-up.
