Operating current measured with I/Os defaulting as GPIs, with all pull-ups enabled and all inputs open.
With one GPI low.
Load = 100 kΩ.
Power-up default current. All I/Os default to GPIs and are open; C8 and C9 default to GPIs; I
GPIO internal pull-ups are approximately 100 kΩ.
Guaranteed by design.
