As noted in Section 1.1, the EVM interfaces with the PHI and communicates with the computer over the USB. There are two devices on the EVM with which the PHI communicates: the ADS8555 ADC (over SPI or parallel) and the EEPROM (over I2C). The electrically erasable programmable read-only memory (EEPROM) comes preprogrammed with the information required to configure and initialize the ADS8555 platform. When the hardware is initialized, the EEPROM is no longer used.
