Question about WDT and 32.768 kHz RC oscillator

Hi again, Jun!

So, if this event of LFXO stopping is to happen, the WDT will stop. Then a pin reset will be needed to recover, as the clock signal is gone.

Best regards,
Mathias

Hi Mathias,

I mean that the crystal oscillator stopped oscillating due to its own reasons(Such as extremely low temperature).

Thanks and regards,

Jun

Hi, Jun!

[quote user=""]If user selected the 32.768 kHz crystal oscillator as LFCLK source clock and enabled and started the WDT and then the 32.768 kHz crystal stopped for physical reasons.[/quote]

Are you then thinking of a situation where the LFXO is physically removed from the PCB?

Best regards,
Mathias
