(1) The leakage current for the Comparator_A+ terminals is identical to I_lkg(Px.y) specification.
(2) Not ensured for T_A > 105°C.
(3) 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.
(4) Response time measured at P2.2/TA0.0/A2/CA4/CAOUT. If the Comparator_A+ is enabled a settling time of 60 ns (typical) is added to
the response time.
