Evaluation Kit Hardware
4.2.3.6
Serial Peripheral Interface (SPI) Controller
The serial processor provides two high-speed Serial Peripheral Interface (SPI) controllers. One port is
used to interface with the on-board serial DataFlash ? .

Two Wire Interface (TWI)
The serial processor has a full speed (400 kHz) master/slave TWI Serial Controller. The controller is
mostly compatible with industry standard I2C and SMBus Interfaces. This port is used to interface with
the on-board Serial EEPROM, ISI, QTouch device and audio codec interface.
