CAN Bus Data Transfer Rate
Various data transfer rates (baud rates) can be set on the CAN bus. The longer the bus line
is, the lower the data transfer rate that must be selected.

These values apply to the following cable: 120
, Twisted Pair.
Note:
For the CAN bus protocol: 1 Kbits/s = 1 kBaud
The Speed setting 00 is for ARM devices and with Intel x86 devices, can
lead to CAN communication problems under some circumstances. For
error-free operation, it is recommended that x86 devices not use this speed
setting.
