    Abstract: The communication apparatus, synchronization serial communication system and the method thereof are provided by the present invention. The communication apparatus and the synchronization serial communication system have an electric level pulling circuit. The synchronization serial communication system and the method thereof reduce the amplitude of the clock signal or the reset signal using the electric level pulling circuit such that the specific slave apparatus can supersede another slave apparatus to exchange data and the serial communication manner is more flexible.

    Abstract: Disclosed are a smart chip (1) and an information processing method thereof. The smart chip (1) includes a MCU (2) and an information processing circuit (3), wherein the MCU (2) including a storage unit (20) and communicating with an image forming apparatus through the information processing circuit (3). The storage unit (20) includes a first memory area (201) to store a set of nonzero amount data which is not overwritable, a second memory area (202) to store an amount data which is updated by the image forming apparatus and a token bit (203) to control the image forming apparatus to read data from the first memory area (201) or the second memory area (202). The information processing method of the smart chip (1) includes steps as follows: judge whether the type of the instruction from image forming apparatus is reading or writing at first; if it is reading, send data according to the state of token bit (203); if it is writing, change the state of token bit (203) according to the content of the instruction. The smart chip (1) and the information processing method thereof according to the present invention make the smart chip can be used repeatedly by providing two memory areas and using a token bit to control reading of data in the memory areas.
