Hi! 

I wish to know what TWDCLK means, like in the case bellow:

When it talks about the minimum and maximum interval to watchdog, what means the TWDCLK, in yellow?

Best regards,

According to the datasheet, the wdt oscillator is the "LPOsc" as far as I can tell.

And that has the following specs:

So the answer must be "approx 1 MHz"

Hello Barbara! 

The answer that Carsten Groen gave is correct. TWDCLK  is the clock of the Windowed Watchdog timer, that corresponds to the LPOsc. If you want to substitute TWDCLK  for the corresponding value you can use 1MHz.

Victor.
