Figure 59 DSP/PCM Mode B, Master Mode, with TDM
DSP/PCM Mode A, Slave Mode: SLOT0 and SLOT1 are defined as shown below. The number of
BCLK cycles from the start of SLOT0 (left) to the start of SLOT1 (left) is determined by the selected
word length of the interface of the WM8352.

13.10.4 LOOPBACK
When the loopback feature is enabled, the audio ADC’s digital output data is looped back to the
audio DAC and converted back into an analogue signal. This is often useful for test and evaluation
purposes.
