21.4.2 Dual delegate
When the dual delegate interface is in the dual delegate
mode, it is a delegate device for 2 delegates. The system
sees the dual delegate interface as two separate devices,
but it gives only one address to the dual delegate
interface. Refer to figure 21.4 for a typical example.
When audio input 1 is enabled, the dual delegate
interface disables audio output 1. When audio input 2 is
enabled, the dual delegate interface disables audio
output 2.
21.4.3 Chairman
When the dual delegate interface is in the chairman
mode, it acts as a chairman device for 1 chairman. You
can connect 2 audio inputs in the chairman mode. Refer
to figure 21.5 for a typical example.
