NOTES:
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. Response time measured at P1.3/CAOUT.
