CCL_IF
Clock Correction Limit Reached Interrupt Flag — This ag is set when the internal calculated offset or rate
calculation values have reached or exceeded its congured thresholds as given by the offset_coorection_out
0 No such event.
1 Offset or rate correction limit reached.
8
MXS_IF
Max Sync Frames Detected Interrupt Flag — This ag is set when the number of synchronization frames
detected in the current communication cycle exceeds the value of the node_sync_max eld in the
Protocol0 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 lters
are taken into account.
7
MTX_IF
Media Access Test Symbol Received Interrupt Flag — This ag is set when the MTS symbol was received
on channel A or channel B.
0 No such event.
1 MTS symbol received.
6
LTXB_IF
pLatestTx Violation on Channel B Interrupt Flag — This ag 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.
5
LTXA_IF
pLatestTx Violation on Channel A Interrupt Flag — This ag 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.
4
TBVB_IF
Transmission across boundary on channel B Interrupt Flag — This ag 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.
3
TBVA_IF
Transmission across boundary on channel A Interrupt Flag — This ag 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.
2
TI2_IF
Timer 2 Expired Interrupt Flag — This ag is set whenever timer 2 expires.
0 No such event.
1 Timer 2 has reached its time limit.
1
TI1_IF
Timer 1 Expired Interrupt Flag — This ag is set whenever timer 1 expires.
0 No such event
1 Timer 1 has reached its time limit
0
CYS_IF
Cycle Start Interrupt Flag — This ag is set when a communication cycle starts.
0 No such event
1 Communication cycle started.
