Can a glitch filtered GPIO wake up a device from power down mode?

I've found when I recently turned on the GPIO glitch filter for my application, I can no longer press the button to wake up from power down mode.

Is this expected? Is it because the IOCON clock running the glitch filter is off during power down mode?

OK, I can wake up the device now after disabling glitch filtering right before power down.

I think you should write about this nuance in the documentation.

Hi,

If you have the glitch filter turned on in the IOCON before entering power-down mode, the IOCON will retain state when in power-down mode.
I would suggest to turn off the glitch filter before going into power-down mode.

Thanks.
