  • DATA BUS CONTROL METHOD AND APPARATUS
    Publication number: 20110208885
    Abstract: A method and apparatus to prevent I2C device from hanging the I2C data bus and thus stopping other devices in the system from transmitting or receiving data is presented. A logic transition detector detects a logic transition at the output data line of an I2C device and triggers a timer. The timer starts counting after it is triggered. A reset module resets the I2C interface module in the I2C device after the timer counts to a specified period of time. The timer is reset when the logic transition detector detects another logic transition at the output data line of the I2C device.
