Bit Name
Description
IU_Zeros[3:0]
Determines the number of zeros to be stuffed between IUs in a message up to a maximum of 8.
0000 = 0.
0001 = 1.
0111 = 7.
1000 = 8.
TxBCONF3
Transmitter user bits can be stored in separate buffers or stored together.
0 = User bits are stored together.
1 = User bits are stored separately.
TxBCONF[2:1]
Configures the transmitter user bit buffer.
00 = Zeros are transmitted for the user bits.
01 = Transmitter user bit buffer size is configured according to TxBCONF0.
10 = User bits are written to the transmit buffer in IUs specified by the IEC60958-3 standard.
11 = Reserved.
TxBCONF0
Determines the buffer size of the transmitter user bits when TxBCONF[2:1] is 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.

Table 42. Channel Status Switch Buffer and Transmitter Register Bit Description
Bit Name
Description
Tx_A/B_Same
Transmitter Channel Status A and B are the same. The transmitter reads only from the Channel Status A buffer and
places the data into the Channel Status B buffer.
0 = Channel status for A and B are separate.
1 = Channel status for A and B are the same.
Disable_Tx_Copy
Disables the copying of the channel status bits from the transmitter channel status buffer to the S/PDIF transmitter
buffer.
0 = Copying transmitter channel status is enabled.
1 = Copying transmitter channel status is disabled.
TxCSSWITCH
Toggle switch for the transmit channel status buffer.
0 = 24-byte Transmitter Channel Status A buffer can be accessed at address locations 0x38 through 0x4F.
1 = 24-byte Transmitter Channel Status B buffer can be accessed at address locations 0x38 through 0x4F.
RxCSSWITCH
Toggle switch for the receive channel status buffer.
0 = 24-byte Receiver Channel Status A buffer can be accessed at address locations 0x20 through 0x37.
1 = 24-byte Receiver Channel Status B buffer can be accessed at address locations 0x20 through 0x37.
