Description
The 24-byte receiver channel status buffer. The PRO bit is stored at address location 0x20, Bit 0. This buffer is read-
only if the channel status is not autobuffered between the receiver and transmitter.
Description
The 24-byte transmitter channel status buffer. The PRO bit is stored at address location 0x38, Bit 0. This buffer is
disabled when autobuffering between the receiver and transmitter is enabled.
Description
This bit is set if the DTS-CD preamble is detected.
This bit is set if the data received through the AES3/S/PDIF receiver is nonaudio data according to the IEC61937
standard or nonaudio data according to SMPTE337M.
This bit is set if the data received through Channel A of the AES3/S/PDIF receiver is subframe nonaudio data
according to SMPTE337M.
This bit is set if the data received through Channel B of the AES3/S/PDIF receiver is subframe nonaudio data
according to SMPTE337M.
Description
Mutes the AES3/S/PDIF transmitter.
Selects the de-emphasis filter for the input data to the sample rate converter.
0 = Transmitter is not muted.
1 = Transmitter is muted.
00 = No de-emphasis.
01 = 32 kHz de-emphasis.
10 = 44.1 kHz de-emphasis.
11 = 48 kHz de-emphasis.
