NOTE:
Don't use any pull up resistor on the ON_OFF* line, it is
internally pulled up. Using pull up resistor may bring to
latch up problems on the ME910C1 power regulator and
improper power on/off of the module. The line ON_OFF*
must be connected only in open collector or open drain
configuration.
In this document all the lines that are inverted, hence have
active low signals are labelled with a name that ends
with”#",”*” or with a bar over the name.
To check if the device has powered on, the hardware line
PWRMON should be monitored.
It is mandatory to avoid sending data to the serial ports
during the first 200ms of the module start-up.
