Data Bit Rate: For setting the data bit rate, click the drop-down
menu and select the value that is used on the connected CAN bus.
This selection is only available if CAN FD is enabled.
User Notes: Additional information with a length of 125 characters
can be entered for each CAN channel. This text is available while
adding and editing routes.
Configuring Custom Bit Rates with Register Values
In Expert mode, you can configure custom bit rates and sample
points with the bit rate definition mode
Set with register values .
If this mode is selected, input fields for the nominal and data bit rate
are provided to enter the register values of the CAN controller. The
previously selected clock frequency is used for both bit rates.
Bit Rate Prescaler: With this input field, the radio of CPI clock
and serial clock frequency is set. For a custom nominal bit rate, it
accepts values from 1 to 1024 and for a custom data bit rate, it
accepts values from 1 to 1024.
Propagation Segment: This time segment is used to compensate
the signal delays over the network. For a custom nominal bit rate, it
accepts values from 1 to 128 and for a custom data bit rate, it
accepts values from 1 to 16.
Phase Segment 1 & 2: The phase segments are used to compensate
edge phase errors at the beginning and end of the bit. For a custom
nominal bit rate, Phase Segment 1 accepts values from 1 to 128 and
Phase Segment 2 accepts values from 1 to 128. For a custom data
bit rate, Phase Segment 1 accepts values from 1 to 16 and Phase
Segment 2 accepts values from 1 to 16.
ReSynch. Jump Width: The Resynchronization Jump Width defines
the maximum extension or shortening of the Phase Segments for
the signal resynchronization. This value has no impact on the bit
rate and sample point calculation. For a custom nominal bit rate, it
