This sounds like you already have received your 7R0 sample? Or do you have remote control to one that is in the China office?
hmm, when is this case an issue?
This is just an issue when you have VOUT switched off and you want to use the ADC to measure the voltage on the IO pins. A floating pin will not give you any meaningful measurement result. But the values are shown on the screen, so for users that are not accustomed to this behavior for example from their multimeter, it would be nicer to show 0V.
Or am I missing some real hard issue with this?
I’m not sure if it is worth adding extra components like FETs just for this case. Once we have the Vout protection, we could just power the internal voltage regulator with 3.3V and keep the Vout protection disabled. This would allow to enable the 1M pulldowns, but keep the Vout-Pin off. But you’d then need some extra command to allow powering Vout from the outside which currently is always possible.
Another way to deal with this would be to use a permanent higher impedance pulldown. Is this leakage still an issue if you use for example a 10Meg pulldown?
I’m currently a bit reluctant to use a permanent 1M solution. But I guess I need to work with the new impedance test function a bit to get a better idea how it behaves and how a permanent pulldown would affect it. So I might change my opinion on this point.
Edit: I guess I should have read the other thread first…
