RMCKF – Recovered Master Clock Frequency
Default = ‘0’
0 – RMCK output frequency is 256*F
1 – RMCK output frequency is 128*F
CHS – Sets which channel's C data is decoded in the Receiver Channel Status register (0Ah).
Default = ‘0’
0 – A channel.
1 – B channel.
If CHS = 0 and TRUNC = 1, both channels' audio data will be truncated by the AUX[3:0] bits indicated in the
channel A Channel Status data. If CHS = 1 and TRUNC = 1, both channels' audio data will be truncated by
the AUX[3:0] bits indicated in the channel B Channel Status data. This will occur even if the AUX[3:0] bits
indicated in the channel A Channel Status data are not equal to the AUX[3:0] bits indicated in the channel
B Channel Status data.
Control2 (02h)
DETCI – D to E status transfer inhibit
Default = ‘0’
0 – Allow update.
1 – Inhibit update.
EMPH_CNTL[2:0] – De-emphasis filter control. See
Default = ‘000’
000 – If the serial audio output port is using the AES3 direct-output format, the de-emphasis filter must re-
main off.
001 – 32 kHz setting.
010 – 44.1 kHz setting.
011 – 48 kHz setting.
100 – 50 μ s/15 μ s de-emphasis filter auto-select on. Coefficients (32, 44.1 or 48 kHz or no de-emphasis fil-
ter at all) match the pre-emphasis and sample frequency indicators in the channel status bits of Channel A.
Thus it is impossible to have de-emphasis applied to one channel but not the other. The de-emphasis filter
is turned off if the audio data is detected to be non-audio data.
GPO0SEL[3:0] – GPO0 Source select. See
Default = ‘0000’
