3.7 Interrupt Control
The L860 module provides four interrupt signals, and the pin definition is as follows:
Enable/Disable RF network
GNSS disable signal
Reserved
Host antenna configuration
detection
Reserved
W_DISABLE1#
The module provides a hardware pin to enable/disable WWAN RF function, and the function can also be
controlled by the AT command. The module enters into the flight mode after the RF function is disabled.
The definition of W_DISABLE1# signal is as below table:
WWAN function is enabled, the module exits the flight mode.
WWAN function is disabled, the module enters flight mode.
Note：
The function of W_DISABLE1# is enabled by default. It can be disabled by customer’s request.
BODYSAR
The L860 module supports BodySAR function by detecting the DPR pin. The voltage level of DPR is high
by default, and when the SAR sensor detects the closing human body, the DPR signal will be pulled down.
As the result, the module then lowers down its emission power to its default threshold value, thus reducing
the RF radiation on the human body. The threshold of emission power can be set by the AT Commands.
The definition of DPR signal is shown in the following table:
The module keeps the default emission power
Lower the maximum emission power to the threshold value of the module.
