Fixed transmission enabling bit（similar to
MODBUS）
 In fixed transmission mode, the first
three bytes of each user's data frame
can be used as high/low address and
channel. The module changes its
address and channel when transmit.
And it will revert to original setting
after complete the process.

IO drive mode (default 1)
 This bit is used to the module
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.

wireless wake-up time

The transmit & receive module
work in mode 0, whose delay time is
invalid & can be arbitrary value.

The transmitter works in mode 1
can transmit the preamble code of
the corresponding time continuously.

When the receiver works in mode 2,
the time means the monitor interval
time (wireless wake-up). Only the
data from transmitter that works in
mode 1 can be received.

FEC switch

After turn off FEC, the actual data
transmission rate increases while
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.
