Production Data

WM8523

PD, Rev 4.1, August 2011

Interface timing is such that the input data and left/right clock are sampled on the rising edge of BCLK.

By setting the appropriate BCLK and LRCLK polarity bits, the WM8523 DAC can sample data on the

opposite clock edges.

The control of audio interface formats and clock polarities is summarised in Table 10.

Audio Data Interface Format

00 = Right justified

01 = Left justified

AIF_WL

Audio Data Word Length

00 = 16 bits

01 = 20 bits

10 = 24 bits

11 = 32 bits

AIF_BCLK_

INV

BCLK Inversion Control

Slave mode:

0 = use rising edge

1 = use falling edge

Master mode:

0 = BCLK normal

1 = BCLK inverted

AIF_LRCLK

_INV

LRCLK Inversion Control

0 = normal polarity

1 = inverted polarity

When AIF_FMT[2:0]=011 (DSP Mode):

0 = mode A (2nd clock)

1 = mode B (1st clock)
