TMS320F2800155-Q1: LIN communication failure

Part Number: TMS320F2800155-Q1

Dear team:

When I am communicating with LIN, LinaRegs.SCIFLR.bit.PE = 1 | and LinaRegs.SCIFLR.bit.FE = 1 errors will be triggered in LIN communication, resulting in the failure to interrupt the communication in LIN. At present, I adopt the method of resetting SWnRESET to solve the problem. But there will still be error frames, that is, the phenomenon of no response from the machine, hello, I would like to ask if there is a better solution? And why LinaRegs.SCIFLR.bit.PE = 1 and LinaRegs.SCIFLR.bit.FE = 1.
