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 GE864-AUTO power regulator and improper functioning of the module. The

line RESET* must be connected only in open collector configuration.

TIP: The unconditional hardware Restart 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* pad with a totem pole output from +1.8V up to +5V

microcontroller (uP_OUT2):
