3.1.1.7 Slot 7: PCM Left Surround Channel

Audio output frame slot 7 is the composite digital audio left surround stream. In the default

state, the STAC9708/11 accepts PCM data from slots 7 and 8 for the surround DACs, for

output to the DAC_OUT pins. As a programming option, PCM data from slots 7 and 8 may be

used to supply data to the primary DACs when slots 6 and 9 are used to drive the surround

DACs. Please refer to the register programming section for details on the multi-channel

programming options.

3.1.1.8 Slot 8: PCM Right Surround Channel

Audio output frame slot 8 is the composite digital audio right surround stream. In the default

state, the STAC9708/11 accepts PCM data from slots 7 and 8 for the surround DACs, for

output to the DAC_OUT pins. As a programming option, PCM data from slots 7 and 8 may be

used to supply data to the primary DACs when slots 6 and 9 are used to drive the surround

DACs. Please refer to the register programming section for details on the multi-channel

programming options.

3.1.1.9 Slot 9: PCM Low Frequency Channel

Audio output frame slot 9 is the composite digital audio low frequency stream used in a multi-

channel application where the STAC9708/11 is programmed to accept the primary DAC PCM

data from slots 6 and 9. As a programming option, PCM data from slots 6 and 9 may be used

to supply data to the surround DACs when slots 7 and 8 are used to drive the primary DACs.

Please refer to the register programming section for details on the multi-channel programming

options.

3.1.1.10 Slot 10: PCM Alternate Left

Audio output frame slot 10 is the composite digital audio alternate left stream used in a multi-

channel application where the STAC9708/11 is programmed to accept the primary DAC PCM

data from slots 6 and 9. Please refer to the register programming section for details on the

multi channel programming options.

3.1.1.11 Slot 11: PCM Alternate Right

Audio output frame slot 11 is the composite digital audio alternate right stream used in a

multi-channel application where the STAC9708/11 is programmed to accept the primary

DAC PCM data from slots 6 and 9. Please refer to the register programming section for

details on the multi channel programming options.
