Table 40 AIF3 Digital Audio Data Control

The WM5102 performs automatic checks to confirm that each AIF is configured with valid settings.

Invalid settings include conditions where one or more audio channel timeslots are in conflict.

If an AIF1 configuration error, AIF2 configuration error or AIF3 configuration error is detected, this can

be indicated using the GPIO and/or Interrupt functions. See “General Purpose Input / Output” and

“Interrupts” for further details.
