TX 2 Enable: Routes S/PDIF Transmitter 2 to
the GPIO1/DMIC_SDA2/SPDIF_OUT2 pin.
0 - The pin functions as GPIO1 or DMIC_SDA2,
according to DMIC2 Enable .
1 - The pin functions as SPDIF_OUT2, regard-
less of DMIC2 Enable .
Reserved
TX 2 Raw Data Mode : Enables AES3 Direct
Mode. In this mode, a direct copy of the received
NRZ data from the HD Audio bus is sent to
S/PDIF transmitter 2.
0 - Normal S/PDIF TX 2 Data Mode.
1 - Enable Raw S/PDIF TX 2 Data Mode.
RX To TX 2 Loopthru : This bit is used to enable
an internal loop through from the S/PDIF RX to
S/PDIF TX 2. The path is a straight digital mux
from input to output. No re-clocking is performed.
0 - Do not loop S/PDIF RX to S/PDIF TX 2.
1 - Enable S/PDIF RX to S/PDIF TX 2 loopthru.
RX A/B Chnl Status Select: Specifies the chan-
nel from which to extract the channel status bits.
‘0’b - Select channel A status.
‘1’b - Select channel B status.
Reserved
TX 1 Raw Data Mode : Enables AES3 Direct
Mode. In this mode, a direct copy of the received
NRZ data from the HD Audio bus is sent to
S/PDIF transmitter 1.
0 - Normal S/PDIF TX 1 Data Mode.
1 - Enable Raw S/PDIF TX 1 Data Mode.
RX Raw Data Mode : Enables AES3 Direct
Mode. In this mode, a direct copy of the received
NRZ data from the S/PDIF receiver including the
C, U, and V bits are transmitted to the HD Audio
bus. The time slot occupied by the Z bit is used
to indicate the location of the block start.
0 - Normal S/PDIF RX Data Mode.
1 - Enable Raw S/PDIF RX Data Mode.
RX To TX 1 Loopthru : This bit is used to enable
an internal loop through from the S/PDIF RX to
S/PDIF TX 1. The path is a straight digital mux
from input to output. No re-clocking is performed.
0 - Do not loop S/PDIF RX to S/PDIF TX 1.
1 - Enable S/PDIF RX to S/PDIF TX 1 loopthru.
