R45 SPDRXCHAN 2 2Dh 7:0 CATCODE [7:0] - Category Code. Refer to S/PDIF specification for details. 00h indicates “general” mode. 3:0 SRCNUM [3:0] - Indicates S/PDIF source number. 5:4 CHNUM1[1:0] - Channel number for sub-frame 1. 00 = Take no account of channel number (channel 1 defaults to left DAC) 01 = channel 1 to left channel 10 = channel 1 to right channel R46 SPDRXCHAN 3 2Eh 7:6 CHNUM2[1:0] Channel number for sub-frame 2. 00 = Take no account of channel number (channel 2 defaults to left DAC) 01 = channel 2 to left channel 10 = channel 2 to right channel 3:0 FREQ[3:0] - Sampling Frequency Indicated Refer to S/PDIF specification IEC60958-3 for details. 0001 = Sampling Frequency not indicated. R47 SPDRXCHAN 4 2Fh 5:4 CLKACU[1:0] - Clock Accuracy of received clock. 00 = Level II 01 = Level I 10 = Level III 11 = Interface frame rate not matched to sampling frequency. 0 MAXWL - Maximum Audio sample word length 0 = 20 bits 1 = 24 bits Audio Sample Word Length. 000: Word Length Not Indicated RXWL[2:0] MAXWL==1 MAXWL== 0 001 20 bits 16 bits 010 22 bits 18 bits 100 23 bits 19 bits 101 24 bits 20 bits 110 21 bits 17 bits 3:1 RXWL[2:0] - 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. R48 SPDRXCHAN 5 30h 7:4 ORGSAMP [3:0] - Original Sampling Frequency. See S/PDIF specification for details. 0000 = original sampling frequency not indicated 0 AUDIO_N - Linear PCM Identification 0 = Data word represents audio PCM samples. 1 = Data word does not represent audio PCM samples. R49 SPDSTAT 31h 1 PCM_N - 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. |
