  • I2C/SMBus start-stop detecting circuit that reduces the likelihood of stalling the bus due to glitches on the data line
    Patent number: 6530029
    Abstract: Effects of glitches on the data line which can cause an I2C bus (or SMBus) interface to invalidate a detected I2C start command or to erroneously detect an I2C start command, which occurs when the data signal transitions from a logic high to a logic low while the clock signal has a logic high, are reduced by detecting the logic state of the data signal when the clock signal next transitions from a logic high to a logic low.
