Hard Mutes the Audio Output for the AES3/SPDIF Receiver
0 = AES3/SPDIF Receiver is not muted
1 = AES3/SPDIF Receiver is muted
The AES3/SPDIF Receiver PLL will accept a Left/Right Clock from one of the four serial ports as the PLL
reference clock
0 = Left/Right Clock generated from the AES3/SPDIF preambles is the reference clock to the PLL
1 = Left/Right Clock from one of the serial ports is the reference clock to the PLL
00 = Playback Port is selected
01 = Auxiliary Input Port is selected
10 = Record Port is selected
11 = Auxiliary Output Port is selected
When the NONAUDIO bit is set, data from the AES3/SPDIF Receiver will not be allowed into the Sample Rate
Converter (SRC). If the NONAUDIO data is due to DTS, AAC, etc. as defined by the IEC61937 standard, then the
data from the AES3/SPDIF Receiver will not be allowed into the SRC regardless of the state of this bit
0 = AES3/SPDIF Receiver data will be sent to the SRC
1 = Data fro the AES3/SPDIF Receiver will not be allowed into the SRC if the NONAUDIO bit is set
When the VALIDITY bit is set data from the AES3/SPDIF Receiver will not be allowed into the SRC
0 = AES3/SPDIF Receiver data will be sent to the SRC
1 = Data from the AES3/SPDIF Receiver will not be allowed into the SRC if the VALIDITY bit is set
If the user bits are formatted according to the IEC60958-3 standard and the DAT Category is detected, the
User Bit interrupt is only enabled when there is a change in the Start (ID) bit.
0 = The User Bit interrupt is enabled in the normal mode.
1 = If the DAT category is detected, the User bit interrupt is only enabled if there is a change in the Start (ID)
bit
This bit determines whether Channel A and Channel B User Bits are stored in the buffer together or
separated between A and B
0 = The User Bits are stored together
1 = The User Bits are stored separately
Defines the function of RxCSBINT
0 = RxCSBINT will be set when a new block of receiver channel status is read, which is 192 audio frames
1 = RxCSBINT will be set only if the first five bytes of the receiver channel status block changes from the
previous channel status block
Defines the User Bit Buffer
00 = User Bits are ignored
01 = Update the second user bit buffer when the first user bit buffer is full
10 = Format the received user bits according to byte 1, bits 4-7, of the channel status if the PRO bit is set. If
the PRO bit is not set format the user bits according to the IEC60958-3 standard
11 = Reserved
Defines the User Bit buffer size if RxBCONF2-1 = 01
0 = 384 Bits with Preamble-Z as the start of the buffer
1 = 768 Bits with Preamble-Z as the start of the buffer
