8.6 Using the Alarm Output GPIO6

The GPIO6 pad, when configured as Alarm Output, is controlled by the GE863 module and will rise

when the alarm starts and fall after the issue of a dedicated AT command.

This output can be used to power up the GE863 controlling microcontroller or application at the alarm

time, giving you the possibility to program a timely system wake-up to achieve some periodic actions

and completely turn off either the application or the GE863 during sleep periods, dramatically reducing

the sleep consumption to few μA.

In battery-powered devices this feature will greatly improve the autonomy of the device.

NOTE: During RESET the line is set to HIGH logic level.
