Clock accuracy. Value indicating the clock accuracy:
Sample frequency. Value indicating the sampling frequency:
Channel number. Value indicating the channel number (see Table 74).
Source number. Value indicating the source number (see Table 75).
General information. Value indicating general information (see Table 76).
Mode. Value indicating mode 0:
Audio sampling. Value indicating the type of audio sampling (linear PCM). For
bit SPDO_BIT1 = 0:
Software copyright. Value indicating software for which copyright is asserted or not.
If this bit is logic 0, then copyright is asserted; if this bit is logic 1, then no copyright is
asserted.
Audio sample word. Value indicating the type of audio sample word. If this bit is
logic 0, then the audio sample word represents linear PCM samples; if this bit is
logic 1, then the audio sample word is used for other purposes.
Channel status. Value indicating the consumer use of the status block. This bit is
logic 0.
