DIGITAL AUDIO INTERFACE - TDM MODE

When TDM operation is used on the AIFnTXDAT pins, it is important that two devices do not attempt

to drive the AIFnTXDAT pin simultaneously. To support this requirement, the AIFnTXDAT pins can be

configured to be tri-stated when not outputting data.

The timing of the AIFnTXDAT tri-stating at the start and end of the data transmission is described in

Figure 8 below.
