(1) The leakage current for the Comparator_A+ terminals is identical to Ilkg(Px.y) specification.
(2) The input offset voltage can be cancelled by using the CAEX bit to invert the Comparator_A+ inputs on successive measurements. The
two successive measurements are then summed together.
(3) Response time measured at P1.3/CAOUT
