::Diode currents of around +/- 240 x 1.414 / 2 m =3D~ 150 uA+ can be=20 ::expected.Well above the "microamp range"=20 Perhaps they were only considering US voltage levels of 110-120? I haven't looked at the specs for an ATMEGA, but on page 7 of the=20 referenced PDF they state the maximum current into a pin is 1mA. If that is= =20 the case, then technically they are correct in their assertion 85 - 160uA=20 is in the microamp range.
