The I2C Hardware User Module implements an I2C device in firmware. The I2C bus is an industry standard, two-wire hardware interface developed by Philips®. The master initiates all communication on the I2C bus and supplies the clock for all slave devices. The I2CHW User Module supports the standard mode with speeds up to 400 kbps. No digital or analog user blocks are consumed with this module. The I2CHW User Module is compatible with other slave devices on the same bus.
