3.10.4. DPR Signal
The module provides a DPR (Dynamic Power Reduction) signal for body SAR (Specific Absorption Rate)
detection. The signal is sent by a host system proximity sensor to the module to provide an input trigger
which will reduce the output power in the radio transmission.

command.
3.11. Antenna Tuner Control Interface*
ANTCTL [0:3] signals are used for antenna tuner control and should be routed to an appropriate antenna
control circuitry.
More details about the interface will be added in the future version(s) of the document.
