Maximum key on duration time（By MOTB pad option） If some objects cover in the sense pad, and causing the change quantity enough to be detected. To prevent this, the TTP232 sets a timer to monitor the detection. The timer is the maximum on duration time. When the detection is over the timer, the system will return to the power-on initial state, and the output becomes i.
