Fast power down
The procedure to power off ME910C1 described in Chapter 5.3 normally takes more than
1 second to detach from network and make ME910C1 internal filesystem properly closed.
In case of unwanted supply voltage loss the system can be switched off without any risk of
filesystem data corruption by implementing Fast Shut Down feature.
Fast Shut Down feature permits to reduce the current consumption and the time-to-
poweroff to minimum values.
NOTE:
Refer to ME910C1 series AT command reference guide (Fast power
down - #FASTSHDN) in order to set up detailed AT command.
5.6.1. Fast Shut Down by Hardware
The Fast Power Down can be triggered by configuration of GPIO_04. HI level to LOW
