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. 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.
