Description
Determines the number of zeros to be stuffed between IUs in a message up to a maximum of 8.
Transmitter user bits can be stored in separate buffers or stored together.
Configures the transmitter user bit buffer.
Determines the buffer size of the transmitter user bits when TxBCONF[2:1] is 01.
Description
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.
Disables the copying of the channel status bits from the transmitter channel status buffer to the S/PDIF transmitter
buffer.
Toggle switch for the transmit channel status buffer.
Toggle switch for the receive channel status buffer.
0000 = 0.
0001 = 1.
…
0111 = 7.
1000 = 8.
0 = User bits are stored together.
1 = User bits are stored separately.
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.
0 = 384 bits with Preamble Z as the start of the buffer.
1 = 768 bits with Preamble Z as the start of the buffer.
0 = Channel status for A and B are separate.
1 = Channel status for A and B are the same.
0 = Copying transmitter channel status is enabled.
1 = Copying transmitter channel status is disabled.
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.
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.
