mitter. To satisfy AC ‘97 2.2 AMAP requirements, the default for these bits will depend on the
Codec ID as shown in Table 9 on page 30. See Table 8 on page 30 for all available Slot Map
settings.
SPDIF_OUT pin. The SPDIF bit routes the left and right channel data from the AC ’97 con-
troller or from the ADC output to the S/PDIF transmitter block. The actual data routed to the
S/PDIF block are controlled through the configuration of the SPSA[1:0] bits and the ASPM bit
in the AC Mode Control Register (Index 5Eh).
Rate Register (Index 2Ch) and the PCM L/R ADC Rate Register (Index 32h). This bit must
be ‘set’ in order to use variable PCM playback or capture rates. The VRA bit also serves as
a powerdown for the DAC and ADC SRC blocks. Clearing VRA will reset the PCM Front DAC
Rate Register (Index 2Ch) and the PCM L/R ADC Rate Register (Index 32h) to their default
values. The SRC data path is flushed and the Slot Request bits for the currently active DAC
slots will be fixed at ‘0’.
S/PDIF Configuration Valid. This read-only bit indicates the status of the S/PDIF transmitter
S/PDIF Slot Assignment. These bits control the mapping of output slots to the S/PDIF trans-
Enable Sony/Philips Digital Interface. This bit enables S/PDIF data transmission on the
Enable Variable Rate Audio. When ‘set’, the VRA bit allows access to the PCM Front DAC
