Hello. I have made a board with S9KEAZN64AMLC microcontroller. Now i started writing code in Kinetis Design Studio and got some trouble. At first i had create a new project for this MCU. Most similar variant in KDS is SKEAZN64MLC2. I choise it. After this i tried to setup core clock frequency but it doesn't allow to set value more then 20MHz(40 mhz in spec). Where are my mistake? Thanks.
