The I2C bus control which separates selection IC for high-speed I2C bus communication

摘要

The system in order to separate IC of specification selectively on I² C the bus system, method, and the device are offered. That at the data rate which is faster I² C bus system than data rates, mutually, and/or, the other components and communicating can do IC of the specification which is separated, by separating IC of specification selectively. The switch, the assistance which accommodates IC where it should separate at the time of a certain mode, or, separates the separate I² C parts selectively, in order for the above-mentioned auxiliary I² C parts to become some of the main I² C bus system parts at the time of another mode, operates. The appropriate pull-up resistance which cooperates with the above-mentioned switch, supports the fact that it operates at a faster data rate description above IC where it is separated, from low speed due to the speed-up change to high speed.
