CYW20819 32.768 kHz xtal test

[ToKo_4602001]

This question is about mass production test.

How can we test if external 32 kHz crystal oscillator works well?

We want a function that returns fail if there is no external xtal and it is broken.

Thanks,

Hello ToKo_4602001​,

We donot have any dedicated function as such to check the working/existence of external crystal. But you can try running a timer and check if crystal is working properly. Please check clock_timer.h file for more details.
