Will be set if the DTS-CD Preamble is detect

NonAudio Frame

This bit will be set if the data received through the AES3/SPDIF Receiver is nonaudio data according to the

IEC61937 standard or nonaudio data according to SMPTE337M

Subframe_A

This bit will be set if the data received through Channel A of the AES3/SPDIF Receiver is subframe nonaudio data

according to SMPTE337M

This is 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.

This is 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.

A read from this register will read 8 bits of user data from the Receiver User bit buffer pointed to by

RxUBADDR7-0. This buffer can be written to when autobuffering of the user bits is enabled otherwise it is a

read only buffer
