Hi team,

I found the description on data sheet that "Spread spectrum clocking to minimize EMI "

But how to open or close this function? I don't find related register.

Hi Hanbing,

Thanks for the post. The SSC feature is hard-coded and enabled full-time in the DRV8899-Q1. It cannot be disabled. There is no register bit control for the SSC feature.
