SNIP_CLASSIC_CAN_SECTION_5_3_System_Services
Wortlaut
5.3 System Services
[SWS_Can_00280] ⌈In special hardware cases, the Can module shall poll for events of the hardware.⌋
[SWS_Can_00281] ⌈The Can module shall use the OsCounter provided by the system service for timeout detection in case the hardware does not react in the expected time (hardware malfunction) to prevent endless loops.⌋ Implementation hint: The blocking time of the Can module function that is waiting for hardware reaction shall be shorter than the CAN main function (i.e. Can_MainFunction_Read) trigger period, because the CAN main functions can’t be used for that purpose.
