Slide switch interface
The form factor of this phone is slide, which means that it has to wake up when it slides open. The slide
operation is sensed by a MR sensor (hall sensor) mounted on the main PWB and a magnet fitted to the sliding
mechanism.
The MR sensor output is active low (0V) and 1.8V when not active. This enables the phone to detect closed
and open position.
The output of the sensor is connected to GenIO38 of RAP3GS2v4.
