For example: The meaning of No.3 "SPED" byte：
7 6
0 0
 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.
 It is transparent transmission under 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
code before 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 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.
 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.
 Low power transmission is not recommended due to its low
power supply efficiency.
