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 GE865 power regulator
and improper functioning of the module. The line RESET# must be connected only in
open collector configuration.
NOTE:
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 of a +3/5
V microcontroller (uP_OUT2):
NOTE:
The RESET# signal is internally pulled up so the pin can be left floating if not used
