4.2 Optional EVM Configuration

Figure 5-2 shows optional connections to the configuration pins, clock, voltage reference and VCM. These connections are not required for initial setup of the EVM but can be helpful to configure the EVM more closely to the user's end application configuration. Review Section 2 and Section 5.1 to understand how these connections are used.
