MASTER AND SLAVE MODE OPERATION
The WM9081 digital audio interface can operate as a master or slave as shown in Figure 34 and
Figure 35.
Figure 34 Master Mode
The Audio Interface output control is illustrated above. BCLK and LRCLK are configured as inputs or
outputs using the BCLK_DIR and LRCLK_DIR register fields - see “Digital Audio Interface Control”.
Note that BCLK and LRCLK can be configured independently as inputs or outputs, allowing mixed
Master/Slave operation.
OPERATION WITH TDM
Time division multiplexing (TDM) allows multiple devices to transfer data simultaneously on the same
bus. The WM9081 DAC supports TDM in master and slave modes for all data formats and word
lengths. TDM is enabled and configured using register bits defined in the “Digital Audio Interface
Control” section.
