4.3 Digital Header

In addition to the PHI, the EVM has a header connected to the digital lines that can be used to connect a logic analyzer or oscilloscope. This placement allows for easy access to the digital communications. Header J7 is connected to the digital lines between the ADS131A04 and the PHI connector. Table 4-2 describes the digital header pins.
