Dear Sir

I would like to confirm the configuration of XMC's High Precision Oscillator Circuit (OSC_HP).
Is it allowed to use XTAL2 as GPIO in direct clock input mode?

Or should XTAL2 always be open?

Hi @NXTY_Inoue ,

In the  External Input Clock Mode the XTAL2 pin is left open that is unconnected and in the  External Crystal Mode the XTAL2 pin is connected with the load circuitry apart of this two modes you can use the XTAL2 as an GPIO.

Hope this helps and let me know if you need any further information.

Best Regards
Pradeep.
