PLL Programming
Figure 6-4.
Figure 6-5.
The PLL is programmed using the flow shown in Figure 6-6. As soon as clock generation is
enabled, the user must wait until the lock indicator is set to ensure the clock output is stable. The
PLL clock frequency will depend on the audio interface clock frequencies.
