The datasheet for the ATxmega64A4 family specifies a max. current per I/O pin of 20 mA, and a max. current for VCC and GND pins of 200 mA. I take this to mean the max. current the device will ever draw is 200 mA, and the 20 mA per I/O pin must come from this budget. It occurs to me, though, that these specs could also be interpreted as meaning the 20 mA per I/O pin is ADDED to the 200 mA to calculate total draw. In my experience that would be unusual, but I just wanted to make sure that is not the case. Thanks.
