Reserved for additional de-emphasis modes.
00 = Only valid mode for consumer applications.
Category Code. Refer to S/PDIF specification for details.
00h indicates “general” mode.
Indicates S/PDIF source number.
Channel number for sub-frame 1.
00 = Take no account of channel number (channel 1 defaults to
left DAC)
Channel number for sub-frame 2.
00 = Take no account of channel number (channel 2 defaults to
left DAC)
Sampling Frequency Indicated
Refer to S/PDIF specification IEC60958-3 for details.
0001 = Sampling Frequency not indicated.
Clock Accuracy of received clock.
Maximum Audio sample word length
Audio Sample Word Length.
000: Word Length Not Indicated
All other combinations are reserved and may give erroneous
operation. Data will be truncated internally when these bits are set
unless WL_MASK is set.
Original Sampling Frequency. See S/PDIF specification for details.
0000 = original sampling frequency not indicated
Linear PCM Identification
Indicates that non-audio code (defined in IEC-61937) has been
detected.
0 = Sync code not detected.
1 = Sync code detected – received data is not audio PCM.
01 = channel 1 to left channel
10 = channel 1 to right channel
01 = channel 2 to left channel
10 = channel 2 to right channel
00 = Level II
01 = Level I
10 = Level III
11 = Interface frame rate not matched to sampling frequency.
0 = 20 bits
1 = 24 bits
0 = Data word represents audio PCM samples.
1 = Data word does not represent audio PCM samples.
