The ADAV803 features a digital in

multiplexing matrix that gives flexibility to the range of possible

input and output connections. Digital input ports include

playback and auxiliary input (both 3-wire digital), and S/PDIF

(single-wire to the on-chip receiver). Output ports in

S/PDIF port (single-wire from the on-chip transmitter).

Internally, the DIR and DIT are interfaced via 3-wire interfa

The datapath for each input and output port is selected by

programming Datapath Control Registers 1 and 2. Figure 52
