Microchip datasheet for the MCP2515, a stand-alone CAN bus controller with an SPI interface. It describes the register map, transmit and receive buffers, filters and masks, bit timing configuration, interrupt pins and electrical characteristics. Technicians and developers use it when servicing automotive modules, industrial controllers or hobby CAN boards, usually paired with a separate transceiver such as the MCP2551. Check the oscillator frequency on your board, because bit-timing settings depend directly on it.
