(1) The leakage current for the Comparator_A+ terminals is identical to I_lkg(Px.x) 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) The response time is measured at P2.2/CAOUT/TA0/CA4 with an input voltage step, with Comparator_A+ already enabled (CAON = 1).
If CAON is set at the same time, a settling time of up to 300 ns is added to the response time.
