FlexRay Communication Controller (FLEXRAY)

Preliminary
30.5.2.31 Sync Frame Counter Register (SFCNTR)
This register provides the number of synchronization frames that are used for clock synchronization in the
last even and in the last odd numbered communication cycle. This register is updated after the start of the
NIT and before 10 MT after offset correction start.
NOTE
If the application has locked the even synchronization table at the end of the
static segment of an even communication cycle, the FlexRay block will not
update the fields SFEVB and SFEVA.
If the application has locked the odd synchronization table at the end of the
static segment of an odd communication cycle, the FlexRay block will not
update the values SFODB and SFODA.

This field provides the size of the internal list of frame IDs of received synchronization frames used for clock
synchronization.
SFODB
Sync Frames Channel B, Odd Cycle. Protocol related variable: size of (
vsSyncIdListB
for odd cycle)
This field provides the size of the internal list of frame IDs of received synchronization frames used for clock
synchronization.
SFODA
Sync Frames Channel A, Odd Cycle. Protocol related variable: size of (
vsSyncIdListA
for odd cycle)
This field provides the size of the internal list of frame IDs of received synchronization frames used for clock
synchronization.
