4.18.7.7.3 Function model 254 - FlatStream
The "FlatStream" function model provides independent communication between an X2X Link master and the mod-
ule. This interface was implemented as a separate function model for the CAN module. CAN information (identifier,
status, etc.) is transferred via cyclic input and output registers. The sequence and control bytes are used to control
this data stream (see 4.18.7.7.11 "FlatStream communication" on page 1632).
Information:
•
The "CAN_Lib" library can't be used.
•
Higher data rates can be achieved between X2X master and module compared to the "Flat"
function model.
