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

Hi Neo,
yes, I have received following...
"The external clock is given by PIT_RTI module channel no.14 and no.15 to FlexCAN modules 0/1/2/3 and 4/5/6/7 respectively.
This information is missing in RM., will be corrected in next RM revision.
Also this is a change in MPC5748G from cut 2 to cut 3."
