When booting a host, a host peripheral system sends a boot code to the host for controlling the booting operation of the host via a serial transmission line, and loads an external program code into the host. After setting up a transmission mechanism through executing the external program code, the host can forward a write command to the host peripheral system for writing the data provided by the external program code to the command identification sector of the non-volatile memory of the host peripheral system, and the host peripheral system is capable of identifying the data as a command and executes functional operations corresponding to the command. After finishing the functional operations, the host peripheral system forwards a finish signal to the host, and the host is able to send a read command for fetching the data signal generated in the functional operations.
