If the stuckat timer is set to one second then the touch of a finger will last only for one second and then a
compensation will be performed and button hence considered released, even if the finger remains on the
button for a longer time. After the actual finger release the button can be touched again and will be reported as
usual.
In case the stuckat timer is not required it can be set to zero.
