Description
The DI2CSB function provides an interface between a target device (e.g., memory, LCD display, pressure sensors) and an I2C bus. It can work as a receiver or transmitter depending on the working mode determined by the master. The DI2CSB function is used in automotive audio-video systems and embedded microprocessor systems.
