Description
TxMUTE
Mutes the AES3/S/PDIF transmitter.
0 = Transmitter is not muted.
1 = Transmitter is muted.
SRC_DEEM[1:0]
Selects the de-emphasis filter for the input data to the sample rate converter.
00 = No de-emphasis.
01 = 32 kHz de-emphasis.
10 = 44.1 kHz de-emphasis.
11 = 48 kHz de-emphasis.

DTS-CD Preamble
This bit is set if the DTS-CD preamble is detected.
NonAudio Frame
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.
NonAudio Subframe_A This bit is set if the data received through Channel A of the AES3/S/PDIF receiver is subframe nonaudio data
according to SMPTE337M.
NonAudio Subframe_B This bit is set if the data received through Channel B of the AES3/S/PDIF receiver is subframe nonaudio data
according to SMPTE337M.

Bit Name
Description
RCSB[7:0]
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.
Transmitter Channel Status Buffer—Address 0111000 to Address 1001111 (0x38 to 0x4F)

Bit Name
Description
TCSB[7:0]
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.
