Hi, pretty sure this is an error in the schematic found on the main Micro reference page - http://arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf ?

In the "+5V Reg" section, PFET T2 is used for reverse polarity protection right?  Shouldn't the gate be connected to GND instead of +5V, as per http://www.youtube.com/watch?v=IrB-FPcv1Dc&t=2m11s]http://www.youtube.com/watch?v=IrB-FPcv1Dc&t=2m11s ?



Also, someone had a micro board and tested it for me - they say that the board is also connected to +5V on that pin - which means reverse polarity protection on this board doesn't work, if my reasoning is right?
