GPIOs in “Low power mode standby” 28027

Hello!

It is not clear to me with happen with my GPIOs, if I enter low power mode. Before entering low power mode I disable all peripheral clocks (including GPIO clock). And I am using WDOG reset to get out of low power mode. So I don’t need a GPIO to wake up.

I was expecting that all GPIOs have high impedance, but I observed (or at least it looks like) that the GPIO output are still active.

Is it allowed/possible to have GPIO outputs active in low power mode? (I assume to GPIO output needs more current, but this would be ok for me.)
