• NOTINCAL: Not in Calibration Mode
0: Calibration should be performed on the next iteration of the DMATouch algorithm.
1: Calibration should not be performed on the next iteration of the DMATouch algorithm.
• DETCNT: Detection Count
This count value is updated and used by the DMATouch algorithm in order to detect when a button has been pushed.
• BASECNT: Base Count
This count value represents the average expected acquired count when the sensor/button is not pushed.
