SNIP_CLASSIC_LINIF_SECTION_7_3_Main_function

7.3 Main function The LinIf_MainFunction_<LinIfChannel.ShortName> is the central processing function in the LIN Interface. It has to be called periodically. For LIN master nodes, the task of the function LinIf_MainFunction_- <LinIfChannel.ShortName> is to poll the Schedule Table Manager, initiate frame transmission and receptions and interact with upper and lower layers. For LIN slave nodes, the task of the function LinIf_MainFunction_- <LinIfChannel.ShortName> is to supervise different timings. It is up to the implementer to decide if the frame handling and interaction with upper and lower layers is handled on task level or inside the LIN interface callback functions. The SchM will call the function LinIf_MainFunction_<LinIfChannel.ShortName> periodically with a period which is given by the configuration parameter LinIfMainFunctionPeriod.
