The measurement period is the combination of measurement time and sleep time.
Measurement time is the total time required to acquire (including oversampling) and
process touch signals of all active buttons. Sleep time occurs between the measurements.
The measurement period can be configured up to 250 milliseconds (ms).Figure 3-2. Active Measurement
