Default：0EH(868M)，The channel interval is
0.5MHz, for example, 861+0.5 x 0EH=868MHz
When it is 1, the first three bytes of each
user data frame can be used as high/low
address and channel. The module changes
its address and channel when transmitting.
And it will revert to original setting after
the process is completed.

continuous mode.
This parameter is only valid for mode 4, 6.
For mode 6, the wake-up time will affect
the WOR cycle of the module, and affect
the power consumption.
For mode 4, the wake-up time decides the
number
of
wake-up
transmission so as to ensure the wake up
the module in mode 6.
Generally, mode 4 and 6 shall be used
jointly and the wake-up time on both
modules shall be the same.
After turn off FEC, the actual data

rate
anti-interference ability decreases. Also,
the transmission distance is relatively
short.
Both communication parties must keep on
the same pages about turn-on or turn-off
FEC.
This bit is used to the internal pull-up
resistor. It also increases the level's
adaptability in case of open drain. But in
some cases, it may need external pull-up
resistor.
The external power must ensure that the
ability of current output is more than 80mA
and the power supply ripple is within
100mV.
