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 Protocol Configuration Register 30 (FR_PCR30).
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 are taken into account.
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.
pLatestTx Violation on Channel B Interrupt Flag — This flag is set when the frame transmission
on channel B in the dynamic segment exceeds the dynamic segment boundary. This is related to
the pLatestTx violation, as described in the MAC process of the FlexRay protocol.
0 No such event.
1 pLatestTx violation occurred on channel B.
pLatestTx Violation on Channel A Interrupt Flag — This flag is set when the frame transmission
on channel A in the dynamic segment exceeds the dynamic segment boundary. This is related to
the pLatestTx violation as described in the MAC process of the FlexRay protocol.
0 No such event.
1 pLatestTx violation occurred on channel A.
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.
