NOTE: don't use any pull up resistor on the RESET*-GSM line nor any totem pole digital output. Using pull up resistor may bring to latch up problems on the GE863-PRO3power regulator and improper functioning of the module. The line RESET*-GSM must be connected only in open collector configuration.

TIP: The unconditional hardware reboot should be always implemented on the boards and software should use it as an emergency exit procedure.

For example:

1- Let's assume you need to drive the RESET*-GSM ( RESET ) pad with a totem pole output of a +1.8/5 V microcontroller (uP_OUT2):

4.4 Turning ON/OFF the GE863-PRO3ARM

To turn on the GE863-PRO3ARM the pad ON/OFF*-APmust be tied low and kept low, when pin is raised ( released ) the ARM will shutdown.

The maximum current that can be drained from the ON/OFF*-APpad is 0,1 mA.
