Abstract
An I2C device is disclosed that includes a main I2C section, bus switches, switch logic, and address logic as part of the I2C device. The I2C device is coupled to an I2C bus for communicating with other I2C devices and an I2C bus controller that is also on the I2C bus. The switch logic controls a current position of the switches. The I2C device is coupled to the I2C bus utilizing the switches. The switches control whether the main I2C section, the address logic, the switch logic, or a combination of the main I2C section, address logic, and switch logic is currently coupled to I2C bus. The switches also can be used, if desired to remove from the buss all devices that are downstream from a given device containing switches. The address logic is used to receive and store the address of the I2C device. The I2C device will respond to the address that is stored in its address logic.
