It is required to drive this line
low by an open drain or open
collector driver connected to
GND.

low impulse width up to 2000ms
(as long as PWR_IND stays low)
It is required to drive this line
low by an open drain or open
collector driver connected to
GND until the module finally
switches off.
If unused keep line open.
Test point recommended.
Note that a low impulse of
more than 2000ms will reset
the module’s RTC.
