Thank you, FvM! This is a cool feature. Good to know!

In between we also tested it. If supplied with 1.2V to a tri-state input pin with weak pull-up, we measured a current of 0.095 mA. If this pin is set as tri-state input without pull-up, no current (<1 uA)) was measured with a normal multimeter. VccIO = 3.0V. If this pin is connected directly with GND, the currents were 0.01 mA and 0.00 mA for both conditions, respectively.
