Hi all

 

According to the table 1 of AN5170, it shows voltage levels in some case of ARM freq.

For example, VDDARM is 0.925V when frequency is 198MHz.

 

Also according to the table 2 of AN4715, it shows voltage levels in some case of ARM freq, too.

For example, VDDARM is 0.95V when frequency is 396MHz.

I have a question about those .

 

Which drivers control those VDDARM's voltage ?
