9 DYCAL Specific settings
9.1 REL_T
The IQS128L has the option to increase the
release threshold when in TM. This helps
that small variations caused by moving a
finger/hand on a touch pad will not cause the
IC to exit TM, making the solution more
robust. The options available are shown
below:

Choosing a proximity event, will make the
activation of OUT more sensitive.
Using a touch event to activate OUT will
make the system less sensitive which is
needed in some applications. The LTA will
still halt with the detection of a proximity but
will not have an influence on the OUT pin.
The LTA will still re-calibrate once a touch
condition is detected.
