Re: Does 12MHz save power?

Sorry. I meant - do you make use of "dynamic voltage scaling" to reduce the CPU supply voltage at lower operating frequencies.
Looking at the STM32L476xx datasheet, there's some mention of it, but it's not clear if it's an optional thing.

Re: Does 12MHz save power?

Do you drop the voltage to the CPU when you drop the operating frequency?
