NOTE: don't use any pull up resistor on the RESET# line nor any totem pole digital output. Using pull
up resistor may bring to latch up problems on the GM862-QUAD power regulator and improper
functioning of the module. The line RESET# must be connected only in open collector configuration.

TIP: The unconditional hardware reset 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# pin with a totem pole output of a +3/5 V
microcontroller (uP_OUT2):

Unconditional Reset
