When written to one, allows the CAT to disable the analog comparators when they are not needed. When written to zero, the
analog comparators are always enabled.
For QMatrix sensors, specifies that discharge will be terminated when CONSEN out of the most recent 5 comparator samples
are positive. For example, a value of 3 in the CONSEN field will terminate discharge when 3 out of the most recent 5 comparator
samples are positive. When CONSEN has the default value of 0, discharge will be terminated immediately when the comparator
output goes positive.
For QMatrix sensors, specifies how many burst prescaler clock cycles the CAT should use to discharge the Cx capacitor at the
end of each burst cycle.
When non-zero, determines the number of prescaled clock cycles between the start of the acquisition on each X line for QMatrix
acquisition.
