S3C44BOX does not have an SPI interface, but it has a SIO interface. The sending and receiving of the SIO module can latch the data bits on the rising edge and the falling edge. Therefore, the rising edge can be achieved by setting the register corresponding to the SIO module of S3C44BOX. Data is sent on the rising edge and received on the falling edge to match the SPI bus timing of the MCP2510. The CAN bus communication circuit is shown in the figure.
