MKV42F256xxx16 maximum clock frequency?

[andreipalamarci]

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.

Hello Andrei Palamarciuc ,

In HSRUN mode , can configure  core clock to highest 168MHZ:

Please see data sheet, in Normal run mode , the Max core clock is 100MHZ.

Hope it helps,

Have a great day,
Alice
