Conversion time
The following table shows the additional time required for each function
(unit: ms).
Math operation Additional time for each point
Moving average 0.045
Scaling 0.055
Peak/bottom hold 0.025

Comparator 0.065
Rate of change 0.030
Cumulative counter 0.035
When using two points, and applying scaling to the first input, and the cumula-
tive counter to the second input, the maximum AD conversion cycle time can
be obtained by using the following formula.
Formula: 2.42 + 0.055 + 0.035 = 2.51 ms
