00000 = Reserved

00001 = Reserved

00010 = 64kHz (58.8kHz)

00011 = 96kHz (88.2kHz)

00100 = 128kHz (117.6kHz)

00101 = 192kHz (176.4kHz)

00110 = 256kHz (235.2kHz)

00111 = 384kHz (352.8kHz)

01000 = 512kHz (470.4kHz)

01001 = 768kHz (705.6kHz)

01010 = 1.024MHz (940.8kHz)

01011 = 1.536MHz (1.4112MHz)

01100 = 2.048MHz (1.8816MHz)

01101 = 3.072MHz (2.8824MHz)

01110 = 4.096MHz (3.7632MHz)

01111 = 6.144MHz (5.6448MHz)

10000 = 8.192MHz (7.5264MHz)

10001 = 12.288MHz (11.2896MHz)

The frequencies in brackets apply for

44.1kHz-related sample rates only.

If AIF3_RATE<1000, then AIF3 is

referenced to SYSCLK and the 44.1kHz-

related frequencies apply if

SAMPLE_RATE_n = 01XXX.

If AIF3_RATE>=1000, then AIF3 is

referenced to ASYNCCLK and the

44.1kHz-related frequencies apply if

ASYNC_SAMPLE_RATE_n = 01XXX.

The AIF3BCLK rate must be less than or

equal to SYSCLK/2, or ASYNCCLK/2, as

applicable.

Table 37 AIF3 BCLK and LRCLK 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.
