Wake-up time
This parameter is only valid for modes 4 and 6;
For mode 6, the wake-up time affects the WOR
period of
the
module and
has a large impact on
power consumption.
For mode 4
,
the wake-up time determines the
number of wake-up codes that the module increases
before launching, so as to ensure that the module in
mode 6 is effectively awakened;
Generally speaking, modes 4
and
6
need to be used
together, and the wake-up time set by both parties
must be consistent.

FEC switch (forward error correction).
After the FEC
is turned off, the actual
data
transmission rate is increased, but the
anti-interference ability is weakened, and the distance
is slightly closer, which is selected according to the
actual application;
Both parties to the communication must be on or off.

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

Transmit power
The external power supply must provide a current
output capability of more
than
80mA and ensure that
the power supply ripple is less than 100mV;
It is not recommended to use smaller power
transmission, and its power utilization efficiency is not
high.

Chapter 8 Parameter Configuration
When the module is in mode 3
(M2, M1,
M0 = 011) or mode 5 (M2, M1
,
M0 = 101), you can configure the module
