time. This feature is enabled by register programming of the various pin selections. Table 5-43 shows the
primary and secondary audio interface selection and registers. Table 5-44 shows the selection criteria for
generating ADC_WCLK. Figure 5-50 is a high-level diagram showing the general signal flow and
multiplexing for primary and secondary audio interfaces. For detailed information, see Table 5-43,
Table 5-44, and the register-definition tables in Section 6.
