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.

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.

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.

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.
Transmission across boundary on channel A Interrupt Flag — This flag is set when the frame transmission
on channel A 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 A.
Timer 2 Expired Interrupt Flag — This flag is set whenever timer 2 expires.
0 No such event.
1 Timer 2 has reached its time limit.
Timer 1 Expired Interrupt Flag — This flag is set whenever timer 1 expires.
0 No such event
1 Timer 1 has reached its time limit
Cycle Start Interrupt Flag — This flag is set when a communication cycle starts.
0 No such event
1 Communication cycle started.
