TxVALIDITY
Description
This bit is used to set or clear the VALIDITY bit in the AES3/S/PDIF transmit stream.
Determines the AES3/S/PDIF transmitter to AES3/S/PDIF receiver ratio.
Selects the clock source for the AES3/S/PDIF transmitter.
Enables the AES3/S/PDIF transmitter.
Description
If the user bits are formatted according to the IEC60958-3 standard and the DAT category is detected, the user bit
interrupt is enabled only when 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.
Defines the function of RxCSBINT.
Defines the user bit buffer.
Defines the user bit buffer size, if RxBCONF[2:1] = 01.
0 = Audio is suitable for digital-to-analog conversion.
1 = Audio is not suitable for digital-to-analog conversion.
000 = Transmitter to receiver ratio is 1:1.
001 = Transmitter to receiver ratio is 1:2.
010 = Transmitter to receiver ratio is 1:4.
101 = Transmitter to receiver ratio is 2:1.
110 = Transmitter to receiver ratio is 4:1.
00 = Internal Clock 1 is the clock source for the transmitter.
01 = Internal Clock 2 is the clock source for the transmitter.
10 = Recovered PLL clock is the clock source for the transmitter.
11 = Reserved.
0 = AES3/S/PDIF transmitter is disabled.
1 = AES3/S/PDIF transmitter is enabled.
0 = User bit interrupt is enabled in normal mode.
1 = If the DAT category is detected, the user bit interrupt is enabled only if there is a change in the start (ID) bit.
0 = User bits are stored together.
1 = User bits are stored separately.
0 = RxCSBINT are set when a new block of receiver channel status is read, which is 192 audio frames.
1 = RxCSBINT is set only if the first five bytes of the receiver channel status block changes from the previous
channel status block.
00 = User bits are ignored.
01 = Updates the second user bit buffer when the first user bit buffer is full.
10 = Formats the received user bits according to Byte 1, Bit 4 to Bit 7, of the channel status, if the PRO bit is set. If
the PRO bit is not set, formats the user bits according to 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.
