FlexRay Communication Controller (FLEXRAY)
22.6.12.1 Sync Frame ID Table Content
The Sync Frame ID Table is a snapshot of the protocol related variables vsSyncIdListA and vsSyncIdListB
for each even and odd communication cycle. This table provides a list of the frame IDs of the
synchronization frames received on the corresponding channel and cycle that are used for the clock
synchronization.
22.6.12.2 Sync Frame Deviation Table Content
The Sync Frame Deviation Table is a snapshot of the protocol related variable zsDev(id)(oe)(ch)!Value.
Each Sync Frame Deviation Table entry provides the deviation value for the sync frame, with the frame
ID presented in the corresponding entry in the Sync Frame ID Table.

22.6.12.3 Sync Frame ID and Sync Frame Deviation Table Setup
The controller writes a copy of the internal synchronization frame ID and deviation tables into the flexray
memory if requested by the application. The application must provide the appropriate amount of flexray
memory for the tables. The memory layout of the tables is given in Figure 22-144. Each table occupies 120
16-bit entries.
