When it is 1, the first 3 bytes of data are
the high address, the low address, and the
channel. When transmitting, the module
changes its own address and channel, and
when it is finished, it restores the original
settings.

This bit is used to enable the internal
pull-up resistor of the module.
Open-drain mode is more adaptable, and
in some cases an external pull-up resistor
may be required.

5 4 3 Wireless wake up time Both the receiving and transmitting
modules work in mode 0. The delay time
is invalid and can be any value.
The transmitter works in mode 1, and
will continue to transmit the wake-up
code for the corresponding time.
The receiver works in mode 2, this time
refers to the receiver's monitoring
interval (wireless wake-up), and can only
receive the data of the transmitting party
working in mode 1.

2 FEC After the FEC is turned off, the actual
data transmission rate is increased, but
the anti-interference performance is
weakened and the distance is closer.
Please choose to turn on or off according
to the actual application.
Both sides of the communication must be
turned on or off at the same time.
