Smartsense tuning

Question: Does smartsense tune the parameters on power on or on reset or intermittently?

 

Answer:

Smart sense Auto Tuning calculates and sets the various parameters which are needed for proper functioning of the sensors.Out of these the following parameters are set during the bootup process i.e when the device is powered on or is reset using XRES:
-DAC compensation
-Prescalar
-Scanning speed
-Resolution

And the below parameters are set dynamically during every scan i.e to say intermittently:
-Finger threshold
-Noise threshold
-Hysterisis
-Negative noise threshold
-Baseline update threshold
