8M Mini Input Current Parameters

The 8M Mini datasheet lists the follow parameters for input leakage current.



Can anyone confirm if the GPIO DC parameters apply to *all* pins configured as GPIO on the 8M Mini? Or do they only apply for the bank of pins labeled "GPIO1"?


Additionally, when the 8M mini powers on and is still being configured, I've noticed larger than expected input currents on GPIO pins (I was expecting a max of 4uA). Is this expected behavior? I would have expected most pins to default to GPIO inputs unless they were configured otherwise, and I'm seeing unconfigured pins pulling much more than 4uA. Finally, what temperature range is the 4uA input current valid for?
