21.7 Debug message handling state machine not reset to Idle when CCCR.INIT is set

When the host sets the MCAN_CCCR.INIT bit through the MCAN_CCCRn register, or when the CAN enters Bus Off state, the debug message handling state machine stays in its current state instead of resetting to Idle state. Setting MCAN_CCCR.CCE does not change MCAN_RXF1S.DMS.

Work Around

If the debug message handling state machine stopped while MCAN_RXF1S.DMS="01" or MCAN_RXF1S.DMS="10", it can be reset to Idle state by hardware reset or by reception of debug messages after MCAN_CCCR.INIT is reset to zero.
