Hello.

I'm working with MKV42F256VLH16 and i'm trying to configure the clock frequency as higher as possible.

As per datasheet it should be possibile to configure the clock up to 168MHz but the MCUXpresso Config Tools v4.1 limit it to 100MHz.

Is this a MCUXpresso Config Tools v4.1 issue or a MKV42F256xxx16 issue?

Thank you for helping.
