10 Application Note
6.0 Buffer Implementation for Audio DAC
A buffer solution to isolate the audio controller when the socket is not configured in ZV Port mode
is shown in Figure 3. This illustrates how to control the buffer enable; if the GD7XXX is used, then
one of the GPO pins can control the buffer enable.
