Can receiver、can module and error frame

Question asked by 罗 文 on Jan 7, 2020

        If I enable the CAN receiver (like TJA1042), but not enable the corresponding CAN module that connect to this CAN receiver, then when I initiate a power on situation, there will appear some error frames.

 

        Can someone explain to me the specific reason why there are can error frames?

 

        Thanks a lot.
