When the module is switched to sleep mode from other modes, if there is data not been processed yet, the module will
process these data (including receiving and sending) before entering sleep mode. This feature can be used for fast sleep
to save power;
For example, the transmitter module works in mode 0, the user transmits the serial port data "12345". At the time, user
does need to wait for the AUX pin to be idle (high level), user can directly switch the module to sleep mode and make
user’s main MCU immediately sleep, then the module will automatically transmit the user data through the wireless, and
will enters sleep mode within 1ms automatically; This will saves MCU's working time and reduces its power
consumption.

Similarly, any mode switching can use this feature. After the module processes the event in the current mode, it will
automatically enter the new mode within 1ms; This saves the user’s work of querying AUX and it achieves the purpose
of fast switching;
For example, switching from the transmit mode to the receive mode; the user MCU can also enter sleep before the mode
switch, and use the external interrupt function to acquire the AUX change, thereby performing mode switching.

This operation mode is very flexible and efficient. It is designed according to the user's MCU's operation convenience,
and it can reduce the workload of the entire system as much as possible, improving system efficiency, and reducing
power consumption as well..
6.2 Normal mode
（
Mode 0
）
Type
When M0 = 0
，
M1 = 0
，
module works in Mode 0
Transmitting
Users can input data through the serial port and the module will start wireless transmission.
Receiving
The module wireless receiving function is turned on, and after receiving the wireless data, it will be output through the serial
port TXD pin.
6.3 WOR mode
（
Mode 1
）
Type
When M0 = 1
，
M1 = 0
，
module works in Mode 1
Transmitting
When defined as the transmitter, the wake-up code for a certain period of time will be automatically added before transmitting
Receiving
Data can be received normally, and the receiving function is equivalent to that in mode 0
6.4 Configuration mode
（
Mode 2
）
Type
When M0 = 0
，
M1 = 1
，
module works in Mode 2
Transmitting
Wireless transmitting off, Automatically open during wireless configuration
