Field MRAF reader - Message RAM access failure The flag is set when the Rx handler: has not completed acceptance filtering or storage of an accepted message until the arbitration field of the following message has been received. In this case acceptance filtering or message storage is aborted and the Rx Handler starts processing of the following message. was unable to write a message to the message RAM. In this case message storage is aborted. In both cases the FIFO put index is not updated. The partly stored message is overwritten when the next message is stored to this location. The flag is also set when the Tx Handler was not able to read a message from the Message RAM in time. In this case message transmission is aborted. In case of a Tx Handler access failure the FDCAN is switched into Restricted Operation Mode (see mode). To leave Restricted Operation Mode, the Host CPU has to reset CCCR.ASM.
