NOTES: 1. The leakage current for the Comparator_A+ terminals is identical to Ilkg(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 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.
