I'd like to know the difference between mk22fn and mk22fx for PLL

[woonkiahn]

What is the difference between mk22fn128 and mk22fx512 at the part of setting PLL

My PLL locking code is working very well on mk22fx512 but it doesn't work on mk22fn128

I'd like to set 96MHz clock with PLL

please someone give a sample code for mk22fn128

Hello Woonki Ahn,

   Actually, you can find the details in the according chip reference manual.

   The problem of your MK22FN128VLH10 PLL is caused by the MK22FN128VLH10 clock system.

This chip just have FLL, no PLL!

Wish it helps you!
