MSPM0G3507-Q1: mspm0G3507 can communication

Part Number: MSPM0G3507-Q1
Other Parts Discussed in Thread: MSPM0G3507

dear sir

we use MSPM0G3507 for one smart sensor project, however we are stucked by MCAN communication.
Appreciated your help look into this case.

1. Does this chip support CAN 2.0A or CAN 2.0B ? how to configure this corresponding registers ?
we cann't find more help information from the demo programm, mcan_message_rx.
here is details information.
-> we use USB2CAN adatpter to emulator host, sending data string to demo kit. we can capture the data wave on oscllicope, And add break point in MCAN0_INST_IRQHandler, but failed to monitor recevie interrupt occurs.
BTW, we use KEIL MDK V5.37.
-> similarily, we try mcan_single_message_tx demo project. it seems all the transmmion is done. but no data wave is found on oscllicope.
-> we also redo the mcan_loopback project on EVK kits. it is done smootly.

2. we note this chip should support CAN 2.0A /CAN 2.0B, CAN FD. can you pls help provide any proven demo project,
which can support classic CAN 2.0. I am not familiar with CAN FD...
