2.1.11 Fast Shutdown
The GPIO4 interface line can be configured as fast shutdown signal line FST_SHDN. The con-
figured FST_SHDN line is an active low control signal and must be applied for at least 1 milli-
seconds. If unused this line can be left open because of a configured internal pull-up resistor.
2.1.12 700MHz Antenna Switch Control
To provide for an antenna optimization over a wide frequency range, the ANT_SWITCH line
may act as a control signal for a possible external antenna switch that is able to change
between an antenna covering the 700MHz band and an antenna covering all other bands -
depending on the frequency band currently being used by the module.
The ANT_SWITCH line is set to "high" (1) if the module is employing frequencies in the 700
MHz range (i.e., LTE band 17) and "low" (0) for all other frequencies, including the 800/850
MHz frequency bands.
The ANT_SWITCH signal is triggered by all module internal activities involving a change of the
used frequency, even if only temporary (e.g., inter-band scanning using compressed mode).
The maximum delay/deviation between internal usage change of the frequency band, and the
GPIO2 signal change is 10 microseconds.
2.1.13 TX Activity Signal
The TX_ACTIVITY line indicates any 2G/3G/4G TX activity of the module, meaning a high level
on this line signals that the module is transmitting data.
