BodySAR_N Pin
ME936 provides an input pin BodySAR_N for BodySAR detection.
It is pulled up internally and when it is pulled low by the proximity sensor output or
controlling signal from host systems, the Tx power reduction actions will be triggered.

If BodySAR_N pin is used to monitor the proximity sensor output, there are some
essential preconditions for this hardware solution.
ME936 cannot provide any control signal for the proximity sensor. Any control or
programming required by the proximity sensor should be handled by the host side.
