juani_c has written an article detailing how to interface the ADS8328 to an MSP430:
The ADS8328 is a high-speed, low power, successive approximation register (SAR) analog-to-digital converter (ADC) that uses an external reference. The ADS8328 has an internal clock that is used to run the conversion but can also be programmed to run the conversion based on the external serial clock, SCLK.
