CAN PE uses peripheral clock

[chai_997128]

1. The CAN PE clock uses a peripheral clock of 60M, and CAN can communicate normally without frequency division

2. When using 12 division frequency and the clock size is 5M, communication cannot be normal.

3. Unable to run correctly when using CAN PE clock and peripheral clock 60M, propagation segment 5, synchronization segment 1 is 3, and synchronization segment 2 is 1

4. When using CAN PE clock and peripheral clock 60M, the transmission segment is 7, synchronization segment 1 is 4, and synchronization segment 2 is 1, it can operate correctly

What is the reason for this? I would like to know how to communicate normally with a 12 division frequency and a clock size of 5M

CTRL->CLKSRC is set to 1.

Are you using s32kF146?

Hi@chai_997128

I didn't find any problem with this configuration, if there is any problem please let me know, I will take some time to test this code

[chai_997128]

hi @Senlent May I ask if there are any results?

[chai_997128]

Under this configuration, CAN cannot operate normally，please help check.thanks！
