For example, most low-end processors provide only one external-interrupt input pin and only one address vector in memory for the service routine that processes external IRQs (interrupt requests).

This paper describes the method of using one accelerometer interrupt pin for both wakeup and non-motion detection to automatically switch on and off the screen. The microprocessor only needs to ...
