Cold Start Abort Interrupt Flag — This flag is set when the configured number of allowed cold start attempts
is reached and none of these attempts was successful. The number of allowed cold start attempts is configured
by the coldstart_attempts field in the
0 No such event.
1 Cold start aborted and no more coldstart attempts allowed.
Missing Rate Correction Interrupt Flag — This flag is set when an insufficient number of measurements is
available for rate correction at the end of the communication cycle.
0 No such event
1 Insufficient number of measurements for rate correction detected
Missing Offset Correction Interrupt Flag — This flag is set when an insufficient number of measurements is
available for offset correction. This is related to the MISSING_TERM event in the CSP process for offset
correction in the FlexRay protocol.
0 No such event.
1 Insufficient number of measurements for offset correction detected.
Clock Correction Limit Reached Interrupt Flag — This flag is set when the internal calculated offset or rate
calculation values have reached or exceeded its configured thresholds as given by the offset_coorection_out
field in the
Configuration Register 14
0 No such event.
1 Offset or rate correction limit reached.
Max Sync Frames Detected Interrupt Flag — This flag is set when the number of synchronization frames
detected in the current communication cycle exceeds the value of the node_sync_max field in the
Configuration Register 30
0 No such event.
1 More than node_sync_max sync frames detected.
Note: Only synchronization frames that have passed the synchronization frame acceptance and rejection filters
Media Access Test Symbol Received Interrupt Flag — This flag is set when the MTS symbol was received
on channel A or channel B.
0 No such event.
1 MTS symbol received.

described in the MAC process of the FlexRay protocol.

pLatestTx
in the dynamic segment exceeds the dynamic segment boundary. This is related to the
described in the MAC process of the FlexRay protocol.
0 No such event.
1
Transmission across boundary on channel B Interrupt Flag — This flag is set when the frame transmission
on channel B crosses the slot boundary. This is related to the transmission across slot boundary violation as
described in the FSP process of the FlexRay protocol.
0 No such event.
1 Transmission across boundary violation occurred on channel B.

Violation on Channel B Interrupt Flag — This flag is set when the frame transmission on channel B
Violation on Channel A Interrupt Flag — This flag is set when the frame transmission on channel A
