Allows easy connection of the core to a microprocessor/microcontroller sys- tem. Control Logic – Manages execution of all commands sent via interface. Synchronizes internal data flow. Shift Register – Controls SDA line, performs data and address shifts during the data transmission and reception. Control Register – Contains five control bits used for performing all types of I2C Bus transmissions. Status Register – Contains seven status bits that indicates state of the I2C Bus and the DI2CM core. Clock Generator – Performs generation of the serial clock. Input Filter – Performs spike filtering. Clock Synchronization – Performs clock synchronization. Arbitration Logic – Performs arbitration dur- ing operations in multi-master systems. Timer – Allows operation from a wide range of the input frequencies. It is programmed by an user before transmission and can be repro- grammed to change the SCL frequency.
