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 not able 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 resp.
the New Data flag for a dedicated Rx Buffer is not set,
a 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
M_TTCAN is switched into Restricted Operation Mode
(see Section 3.1.5). To leave Restricted
Operation Mode, the Host CPU has to reset
CCCR.ASM.
0= No Message RAM access failure occurred
1= Message RAM access failure occurred

Message stored to Dedicated Rx Buffer
The flag is set whenever a received message has
