This parameter is only valid for modes 4 and 6;
For mode 6, the wake-up time affects the WOR
period of
power consumption.
For mode 4
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
together, and the wake-up time set by both parties
must be consistent.
After the FEC
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.
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.
The external power supply must provide a current
output capability of more
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.
