Other Parts Discussed in Thread: TCAN4550
Hello,
a while ago someone asked how to set the bit timing on the TCAN4550 for a data rate of 8Mbps. There was a final answer given and the thread is closed, but the answer doesn't match the description in the TCAN45xx Software User's Guide.
According to the forum thread the bit timing shall be set as follows, assuming a 40MHz clock and a sample point of 80% (The given values are not the register values, that are one less of course):
Bit Rate Prescaler: 1
Time Segment Before Sample Point: 3
Time Segment After Sample Point: 2
Synchronization Jump Width: 2
But according to the Software User's Guide the synchronization segment of 1 time quanta must be considered as well. That means the values above result in a bit time of 6 time quanta's and a data rate of 6.67Mbps. Considering the synchronization segment the bit timing would be:
Bit Rate Prescaler: 1
Time Segment Before Sample Point: 3
Time Segment After Sample Point: 1
Synchronization Jump Width: 1
Can someone clarify which settings are correct? Does the "Time Segment Before Sample Point" on the TCAN4550 includes the synchronization segment or not?
Thank you in advance.
Regards
Sven
