Is this hack credible for resetting the Leonardo's ethernet chip?

@BitSeeker

That's the specification for source current taken directly out of the 32u4 Datasheet

Let me show you what the data sheet says:-

Note where it says This is a stress rating only and also where it talks about operation at these values is not assured. So that means anything over 20mA.

@BitSeeker

I was writing under the (possibly now erroneous) assumption that sink current capability would be the same as source current.

That is correct.

But there are restrictions on groups of pins and port numbers.
