Digital Audio Interface
Group B Connections – Data Signals
Group B connections, shown in
, are used to route signals to
serial data inputs. The serial data inputs to both the A and B channels of
the SPORTs and to each of the eight IDP channels are selected from the
list of Group B sources and set in the Group B registers. When a SPORT
is not configured to receive, the data source set here is ignored. Likewise,
when channel 0 of the IDP is used for the PDAP, the serial data source set
here is ignored.
