TDMCA Frame
In general, the TDMCA frame consists of the command field, extended command (EMD) field, and audio data fields. All
of them are 32 bits in length, but the lowest byte has no meaning. The MSB is transferred first for each field. The command
field is always transferred as the first packet of the frame. The EMD field is transferred if the EMD flag of the command field
is HIGH. If any EMD packets are transferred, no audio data follows the EMD packets. This frame is for quick system
initialization. All devices of a daisy chain should respond to the command field and extended command field. The DSD1792
has two audio channels that can be selected by OPE (register 19). If the OPE bit is not set HIGH, those audio channels
are transferred. Figure 55 shows the general TDMCA frame. If some DACs are enabled, but corresponding audio data
packets are not transferred, the analog outputs are unpredictable.
