Figure 3-31. Sync Frame Table Configuration, Control, Status Register (SFTCCSR)
Sync Frame Table Offset — Offset of the Sync Frame Tables in the FRM. This offset is required to be 16-bit
aligned. Thus STF_OFFSET[0] is always 0.

Even Cycle Tables Lock/Unlock Trigger — This trigger bit is used to lock and unlock the even cycle tables.
0 No effect
1 Triggers lock/unlock of the even cycle tables.
Odd Cycle Tables Lock/Unlock Trigger — This trigger bit is used to lock and unlock the odd cycle tables.
0 No effect
1 Triggers lock/unlock of the odd cycle tables.
Cycle Number — This field provides the number of the cycle in which the currently locked table was
recorded. If none or both tables are locked, this value is related to the even cycle table.
Even Cycle Tables Lock Status — This status bit indicates whether the application has locked the even
cycle tables.
0 Application has not locked the even cycle tables.
1 Application has locked the even cycle tables.
Odd Cycle Tables Lock Status — This status bit indicates whether the application has locked the odd cycle
tables.
0 Application has not locked the odd cycle tables.
1 Application has locked the odd cycle tables.
Even Cycle Tables Valid — This status bit indicates whether the Sync Frame ID and Sync Frame Deviation
Tables for the even cycle are valid. The FlexRay module clears this status bit when it starts updating the
tables, and sets this bit when it has finished the table update.
0 Tables are not valid (update is ongoing)
1 Tables are valid (consistent).
Odd Cycle Tables Valid — This status bit indicates whether the Sync Frame ID and Sync Frame Deviation
Tables for the odd cycle are valid. The FlexRay module clears this status bit when it starts updating the tables,
and sets this bit when it has finished the table update.
0 Tables are not valid (update is ongoing)
1 Tables are valid (consistent).
