WebCAN bus physical & data link layer (OSI) In more technical terms, the controller area network is described by a data link layer and physical layer. In the case of high speed CAN, ISO 11898-1 describes the data link layer, while ISO 11898-2 describes the physical layer. The role of CAN is often presented in the 7 layer OSI model as per the illustration. WebApr 6, 2024 · To this end, the CAN peripheral on the STM32F091 has a series of filter banks that can be used to selectively accept different message types. The general structure of the filters is that you have an ID register used to input the data you want to match against, and then a mask register that defines which bits of ID register are to be matched.
