By default the ASI is using a common sensitivity for all capacitive sensors as in the usual case overlay material
and sensors sizes are about equal. The register bits CapSensitivity0_1[7:4] determine the sensitivity for all
sensors in common sensitivity mode.
It might be required to have a different, individual, sensitivity for each CAP pin (for example proximity sensor
set to max sensitivity while touch sensors are set to a lower one). This can be obtained by setting
CapModeMisc[2:0] to “100” The individual sensitivity mode results in longer sensing periods than required in
common sensitivity mode.
The CAP pins can be set as a button, part of a slider or disabled depending on the application.
