Phenomenon: set receive remote frame = ifxmultican_ Frame_ When can MSG appears in the remote answer, the hardware will automatically reply after receiving the remote frame, resulting in the ID number of the RTR frame being cleared automatically. If the automatic response is turned off, the RTR frame will not be received.


Question: how to turn off auto answer RTR frame and receive RTR frame normally

I tested both tc297 and tc234lp with the same problem.

Hope experts can help me!

When the message object is in "IfxMultican_Frame_remoteAnswer" mode you can disable automatic response to a remote frame by clearing the TXEN0 bit. With the iLLDs it looks like this:
IfxMultican_MsgObj_clearStatusFlag(hwObj, IfxMultican_MsgObjStatusFlag_transmitEnable0);

A receive interrupt (if enabled) will still occur for the message object.
