This example demonstrates how the C8051F06x SMBus interface can communicate

// with a 256 byte I2C Serial EEPROM (Microchip 24LC02B).

// - Interrupt-driven SMBus implementation

// - Only master states defined (no slave or arbitration)

// - Timer4 used by SMBus for SCL low timeout detection

// - SCL frequency defined by <SMB_FREQUENCY> constant
