Recovered Frequency Flag
Indicates recovered S/PDIF clock frequency:
00 = 192kHz
01 = 96kHz or 88.2kHz
10 = 48kHz or 44.1kHz
11 = 32kHz
Unlock Flag
Indicates that the S/PDIF Rx clock recovery
circuit is unlocked.
0 = Locked onto incoming S/PDIF stream.
1 = Not locked onto the incoming S/PDIF
stream.
Use Of Channel Status Block
0 = Consumer Mode
1 = Professional Mode
The WM8804 is a consumer mode device.
Detection of professional mode may give
erroneous behaviour.
Linear PCM Identification
0 = Data word represents audio PCM samples.
1 = Data word does not represent audio PCM
samples.
Copyright Information
0 = Copyright is asserted for Rx data.
1 = Copyright is not asserted for Rx data.
Additional Format Information
0 = Recovered S/PDIF data has no pre-
emphasis.
1 = Recovered S/PDIF data has pre-emphasis.
Reserved for additional de-emphasis modes.
Channel Status Mode
00 = Only valid mode for consumer
applications.
Category Code
Refer to S/PDIF specification (IEC 60958-3) for
full details.
0x00h indicates “general” mode.

S/PDIF Source Number
Refer to S/PDIF specification (IEC 60958-3) for
full details.
Channel Number For Sub-frame 1
00 = do not use channel number
01 = channel 1 to left channel
10 = channel 1 to right channel
Channel Number For Sub-frame 2
00 = do not use channel number
01 = channel 2 to left channel
10 = channel 2 to right channel
Indicated Sampling Frequency
Refer to S/PDIF specification (IEC 60958-3) for
full details.
