(The termination method of CS8900A network card driver based on embedded Linux 2.4.18 is introduced. By connecting the Ethernet device CS8900A to the bus of the embedded microcontroller S3C2410X, the network interface is widened. According to the circuit schematic diagram, the registers BWSCON and BANKCON3 are set to make the network card work in the memory mode, and the interrupt function and related driver codes are written.)
