DIGITAL AUDIO INTERFACE CONFIGURATION ERROR STATUS OUTPUT

GPn_FN = 28h, 29h, 2Ah.

The WM5102 performs automatic checks to confirm that AIF1, AIF2 and AIF3 are configured with

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

conflict.

If an invalid AIF1, AIF2 or AIF3 configuration is detected, this can be indicated using the GPIO and/or

Interrupt functions.

The AIF Configuration Error signals may be output directly on any GPIO pin by setting the respective

GPIO registers as described in “GPIO Control”.

The AIF Configuration Error signals are an input to the Interrupt Controller circuit. An interrupt event is

triggered on the rising and falling edges of the AIF Configuration Error signal. The associated interrupt

bit is latched once set; it can be polled at any time or used to control the IRQ signal. See “Interrupts”

for more details of the Interrupt event handling.
