Can bus timing register
WebAn MCP2515 has only two registers that affect the CAN-controller and govern operating modes, provide buffer-interrupt signals, and set clock parameters. The datasheet calls all these bytes “registers,” so I’ll use that term from now on. An MCP2515 includes other registers that control flag bits and CAN bus bit rates. WebEach CAN unit connected to the bus can be called a node. All CAN units are connected to a bus terminated at each end with 120 Ω resistors to form a network. The bus consists of CAN_H and CAN_L lines. The CAN controller determines the bus level based on the difference in the power level on both wires.

http://www.bittiming.can-wiki.info/ WebJul 4, 2024 · Bus timing register 1 (btr1) defines the length of a bit period, the location of sampling points and the number of samples at each sampling point. In reset mode, this register is accessible (read/write). In Pelican operation mode, this register is read-only. When reading this register in basic can operation mode, the value read is always ‘FFH’.
