Set C0MIDLm and

Cautions 1. The TRQ bit should be set after the RDY bit is set.
Remarks 1. Check the MBON bit at the start and end of the interrupt routine to see if the message buffer and
Data frame
2. The RDY bit and TRQ bit should not be set at the same time.
2. If the TOVF bit is set (1) again, the transmit history list contradicts. Therefore, scan all the
transmit history register can be accessed, because a CAN sleep mode transition request which
has been held pending may be under execution. If the MBON bit is cleared (0), stop the
processing under execution. Re-execute the processing after the MBON bit is set (1) again. It is
therefore recommended to cancel the CAN sleep mode transition request before executing
transmission interrupt servicing.
