Preliminary
30.5.2.34 Sync Frame ID Rejection Filter Register (SFIDRFR)
This register defines the Sync Frame Rejection Filter ID. The application must update this register outside
of the static segment. If the application updates this register in the static segment, it can appear that the
FlexRay block accepts the sync frame in the current cycle.
OVAL
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 block 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).
OPT
One Pair Trigger. This trigger bit controls whether the FlexRay block writes continuously or only one pair of
Sync Frame Tables into the FRM.
If this trigger is set to 1 while SDVEN or SIDEN is set to 1, the FlexRay block writes only one pair of the
enabled Sync Frame Tables corresponding to the next even-odd-cycle pair into the FRM. In this case, the
FlexRay block clears the SDVEN or SIDEN bits immediately.
If this trigger is set to 0 while SDVEN or SIDEN is set to 1, the FlexRay block writes continuously the enabled
Sync Frame Tables into the FRM.
0 Write continuously pairs of enabled Sync Frame Tables into FRM.
1 Write only one pair of enabled Sync Frame Tables into FRM.
SDVEN
Sync Frame Deviation Table Enable. This bit controls the generation of the Sync Frame Deviation Tables. The
application must set this bit to request the FlexRay block to write the Sync Frame Deviation Tables into the
FRM.
0 Do not write Sync Frame Deviation Tables
1 Write Sync Frame Deviation Tables into FRM
Note: If SDVEN is set to 1, then SIDEN must also be set to 1.
SIDEN
Sync Frame ID Table Enable. This bit controls the generation of the Sync Frame ID Tables. The application
must set this bit to 1 to request the FlexRay block to write the Sync Frame ID Tables into the FRM.
0 Do not write Sync Frame ID Tables
1 Write Sync Frame ID Tables into FRM

SYNFRID
Sync Frame Rejection ID. This field defines the frame ID of a frame that must not be used for clock
synchronization. For details see
