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. The response time is measured at P1.6/CA0 with an input voltage step and the 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.
