• Description: Flexray Communication Controllers
• Manufacturer: Freescale Semiconductor, Inc

updated by the FlexRay module after the end of the NIT and before the end of the first slot of the next
communication cycle. The Symbol Window related status bits STCB, SBVB, SSEB, MTB, STCA, SBVA,
SSEB, and MTA are updated by the FlexRay module after the end of the symbol window and before the
end of the current communication cycle. If no symbol window is configured, the symbol window related
status bits remain in their reset state. The clock synchronization related CLKCORRFAILCNT is updated
by the FlexRay module after the end of the static segment and before the end of the current communication
cycle.

NIT Boundary Violation on Channel B — protocol related variable:
This status bit is set when there was some media activity on the FlexRay bus channel B at the end of the NIT.
0 No such event
1 Media activity at boundaries detected
NIT Syntax Error on Channel B — protocol related variable:
This status bit is set when a syntax error was detected during NIT on channel B.
0 No such event
1 Syntax error detected
Symbol Window Transmit Conflict on Channel B — protocol related variable:
window on channel B
This status bit is set if there was a transmission conflict during the symbol window on channel B.
0 No such event
1 Transmission conflict detected
Symbol Window Boundary Violation on Channel B — protocol related variable:
window on channel B
This status bit is set if there was some media activity on the FlexRay bus channel B at the start or at the end of
the symbol window.
0 No such event
1 Media activity at boundaries detected
Symbol Window Syntax Error on Channel B — protocol related variable:
on channel B
This status bit is set when a syntax error was detected during the symbol window on channel B.
0 No such event
1 Syntax error detected
Media Access Test Symbol MTS Received on Channel B — protocol related variable:
Symbol Window on channel B
This status bit is set if the Media Access Test Symbol MTS was received in the symbol window on channel B.
0 No such event
1 MTS symbol received
NIT Boundary Violation on Channel A — protocol related variable:
This status bit is set when there was some media activity on the FlexRay bus channel A at the end of the NIT.
0 No such event
1 Media activity at boundaries detected
NIT Syntax Error on Channel A — protocol related variable:
This status bit is set when a syntax error was detected during NIT on channel A.
0 No such event
1 Syntax error detected
