Pre-Production
w
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.

BCLK Inversion Control
Slave mode:
0 = use rising edge
1 = use falling edge
Master mode:
0 = BCLK normal
1 = BCLK inverted
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)
