(21) CAN0 message configuration register m (C0MCONFm)
Remark A remote frame is received and stored, regardless of the setting of the OWS and DN bits. A

The “message buffer that has already received a data frame” is a receive message buffer whose the
C0MCTRLm.DN bit has been set to 1.
The RTR bit specifies the type of message frame that is transmitted from a message buffer defined
as a transmit message buffer. Even if a valid remote frame has been received, the RTR bit of the
transmit message buffer that has received the frame remains cleared to 0. Even if a remote frame
whose ID matches has been received from the CAN bus with the RTR bit of the transmit message
buffer set to 1 to transmit a remote frame, that remote frame is not received or stored (interrupt
generated, DN flag set, the MDLC0 to MDLC3 bits updated, and recorded to the receive history list).
Other than above
remote frame that satisfies the other conditions (ID matches, the RTR bit = 0, the
C0MCTRLm.TRQ bit = 0) is always received and stored in the corresponding message buffer
(interrupt generated, DN flag set, the C0MDLCm.MDLC0 to C0MDLCm.MDLC3 bits updated,
and recorded to the receive history list).

data frame. The newly received data frame is discarded.
The message buffer that has already received a data frame is overwritten by a newly received data
frame.
