Handle missing external clock, either fallback to internal oscillator or switching off output

[pignoniG]

Hi, is there any recommendation or plan on implementing automatic switch between external and internal reference?
It would be nice to be able to turn off the output if no reference is connected or switch to the internal one.
Thanks

This will require external circuitry. Easiest approach is a diode detector on the external input, and if the level is satisfactory you put a pin on the microcontroller high. Then the program needs to take into account this and switch. Has been done and works ok. BR Thomas fre. 7. juli 2023 kl. 16:31 skrev Giovanni ***@***.***>:

Hi Thomas, I can reliably “sense” the ext reference but didn’t manage to reliably reconfigure the ic wile it’s running. Do you have any example code? Thanks
