I need a controller with a clock accuracy better than what the internal clocks can deliver so I need to connect an external clock signal.

  • What is the frequency range of an external clock at EXTAL0?
  • I am currently using a FRDM evaluation kit. Is there any example code available, how to set the KL02 up to run on the higher frequency. I understand that default settings are using the external 32.768kHz crystal in conjunction with the internal clock generator


Thanks in advance, Tim
