Figure 56 DSP Mode Audio Interface (mode B, AIF_LRCLK_INV=1, Slave)

Mono mode operation is available in DSP interface mode. When Mono mode is enabled, the audio

data is transmitted or received starting on either the 1st (mode B) or 2nd (mode A) rising edge of BCLK

following a rising edge of LRCLK.

PCM operation is supported in DSP interface mode. WM8994 ADC data that is output on the Left

Channel will be read as mono PCM data by the receiving equipment. Mono PCM data received by the

WM8994 will be treated as Left Channel data. This data may be routed to the Left/Right DACs using

the control fields described in the

“Digital Mixing” and “Digital Audio Interface Control” sections.
