MPC574xG : questions about FlexCAN time stamp

Hello Sir,

For the MPC574xG family's FlexCAN time stamp, I have several questions like below.

 

1. When I set the CAN_0.CTRL2.B.TIMER_SRC, free running timer did not increased, and I confirmed this on our EVB. I set this bit field in freeze mode. Is there anything that I missed?

2. What is exact meaning of "external time tick" which is described in CTRL2 TIMER_SRC bit field description? is it mean FXOSC? please let me know the details about "external time tick".

3. I can't find CAN_0.CTRL2.B.TIMER_SRC on Laughterbach peripheral register monitor (View--> peripheral). If my PER file is old, would you please share with me the latest PER file for Calypso 6M and 3M family?

4. It seems that only MPC574xG family's FlexCAN has TIMER_SRC bit field. Is it right? Cobra55 and Rainier don't have TIMER_SRC.

 

Hope to receive any feedback!

 

Best regards,

Neo
