I am using the KL17 microcontroller in recent days. Now I meet a problem. The question is:can the KL17 work without external oscillator? In other words,if the EXTAL0 and XTAL0 pins are floating that connect to nothing,will the KL17 work normally? If the KL17 can,how should I set up the KL17 in the program? I have set MCG to HIRC mode or LIRC2M mode,but the KL17 didn’t work.
I need your help urgently. Who can help me?
