minimum duration at 3.3V must be applied.
signal. To wake the module, a pulse of minimum 250 us at 3.3V must be applied.
To achieve the lowest power consumption (4uA) in sleep mode connect a weak pull down (100K resistor to GND)
on the following pin.
If GPIO-8 through GPIO-4 are being used to drive an output, connect a 100k pull down resistor. Any GPIOs not
used (No connect) can be left floating.
Other GPIO lines: No pulldown needed, internal pulldown ( 80K ) already on chip.
