Data transmission method and game system constructed by using the method

Data transmission system and game system using the same

Serial transmission data is divided into an odd-numbered bit sequence and an even-numbered bit sequence. Each bit of the odd-numbered bit sequence data is distributed respectively between pulses of a first pulse sequence signal having a constant interval, thereby forming a first pulse sequence signal (SDCKA). Each bit of the even-numbered bit sequence data is distributed respectively between pulses of a second pulse sequence signal having a constant interval, thereby forming a second pulse sequence signal (SDCKB). The respective time axes are adjusted such that the clock component of the first pulse sequence signal is located in the data section of the second pulse sequence signal, and the clock component of the second pulse sequence signal is located in the data section of the first pulse sequence signal. Data is transmitted using these adjusted first and second pulse sequence signals (SDCKA, SDCKB).

System for peripheral identification obtained by calculation and

A peripheral device for use with a data processing apparatus. The apparatus has a peripheral port with a set of terminal pins consisting of first to ninth pins disposed in a row. The first pin is assigned for one of a power source and the ground potential, the ninth pin for the other of the power source and the ground potential, the second, third, seventh and eighth pins for transmitting data signals, and the fourth to sixth pins for transmitting control signals. The apparatus has an element for selecting the communication mode of the peripheral device connected to the peripheral port, based on the data signals transmitted from the second, third, seventh and eighth pins. The peripheral device comprises a plug connector detachably connected to the peripheral port, the plug connector having a set of terminal pins consisting of first to ninth pins disposed in a row, a cable including a plurality of wires connecting the terminal pins of the plug connector with terminals on an internal printed circuit board, and an element for transmitting data signals including identification data representing the communication mode via at least one of the second, third, seventh and eighth pins in synchronization with a clock signal supplied from the apparatus.
