Host
Note: The voltage level on VCC_IO_HOST depends on the host side due to the open drain in pin 23.

3.10.5. DPR*

RM502Q-GL provides a DPR (Dynamic Power Reduction) pin for body SAR (Specific Absorption Rate)
detection. The signal is sent from a host system proximity sensor to RM502Q-GL module to provide an
input trigger, which will reduce the output power in radio transmission.

NOTE
Please refer to document [2] for more details about AT+QCFG="sarcfg" command.

3.10.6. STATUS*

RM502Q-GL provides two status indication pins for communication with IPQ807x device. Pin 38
(SDX2AP_STATUS) outputs the status indication signal to IPQ807x device, and pin 68
(AP2SDX_STATUS) inputs the status indication signal from IPQ807x device.
