I can't tell you which without knowing what project you are referring to. You will need to look through how your MCG, SIM, OSC, and/or RTC OSC registers are configured to determine whether internal or external sources are being used and how they are being used.</P></BODY></HTML> Mon, 18 Jul 2016 19:07:09 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/FRDM-K22F-oscillator/m-p/580069#M34379 charlesasquith 2016-07-18T19:07:09Z
