Abstract: A method may include generating display driver signals that vary between only two levels and applying the display driver signals to opposing electrodes of a display segment within a display device. The method varies a correlation between the display driver signals to select or de-select the display segment based on an average voltage magnitude across the display segment over a time period. The display segment is activated when the average voltage magnitude exceeds a threshold value.

Abstract: A method and apparatus to operate a watchdog timer having a first time out period in a processing system. The watchdog timer receives an indication of a change in a mode of operation in the processing system. In response to the change in the mode of operation of the processing system, the watchdog timer changes the time out period to a second time out period corresponding to the new mode of operation.
