In mode 2, it is required the data transmitter works in mode 1.
The wireless module monitors the preamble code at regular time.
Once it gets the preamble code, it will remain as receiving status and waiting for the completion of receiving the entire
valid data package.
Then the AUX outputs low level, 5ms later the serial port is open to transmit received wireless data through TXD.
Receiving
Finally, AUX outputs high level after process completed.
The wireless module stays in "power-saving – monitoring" working status (polling).
By setting different wake-up time, the module will have different receiving response delay (2s in maximum) and average
power consumption (30uA in minimum).
The user needs to achieve a balance between communication delay time & average power consumption.

When the mode changes from stand-by mode to others, the module will reset its parameters, during which the AUX
Notes keeps low level and then outputs high level after reset completed. It is recommended to check the AUX rising edge for
user.
