Abstract
A touch status monitor method includes detecting a touch on a touch screen when operating in a low-power detect scan mode. The method further includes, in response to detecting the touch, switching from the low-power detect scan mode to a low-power active scan mode and labeling the current event as a touch down event. The method further includes, in response to labeling the current event as the touch down event, applying a lock to prevent updating a baseline when entering the low-power detect scan mode. And the method further includes, in response to detecting that the touch has left the touch screen, releasing the lock, labeling the current event as a touch up event, switching from the low-power active scan mode to the low-power detect scan mode, and updating the baseline.
