imx6 CAN
what's the meaning of Propagation Segment?
The description is :
This 3-bit field defines the length of the Propagation Segment in the bit time. The valid programmable
values are 0-7. This field can only be written in Freeze mode as it is blocked by hardware in other modes
Propagation Segment Time = (PROPSEG + 1) * Time-Quanta.
Time-Quantum = one Sclock period.
What's the connection with the setting of bittiming?

Hi
FlexCan bit time is subdivided into three segments (PROPSEG defines Time Segment1),
depicted on Figure 26-2. Segments within the Bit Time i.MX6DQ Reference Manual
http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf
whose meaning is described in specification documents ISO/DIS 11519-1,
Section 10.3 and Bosch CAN 2.0A/B protocol specification dated September 1991.
Best regards
