Windows CE has a number of features to keep power consumption to a minimum in handheld and portable devices. It automatically puts the processor in Idle mode when it is not needed, and has features to dim the backlight or place the system in Sleep mode if it has not been used for a pre-determined amount of time.
Once asleep, ADS systems must be awakened by shorting the RqOnOff input to system ground. This generates the interrupt needed to wake up the processor. There are other methods to wake up the system, including waking at regular intervals and tapping the touch panel (available on our newer products, like the Bitsy Plus).
Consult your user manual for product-specific details concerning power and power management. For example, the Bitsy Plus and AGX user's manuals have a chapter dedicated to power management design.
