SLOT 2: COMMAND DATA PORT
The command data port is used to deliver 16-bit control register write data in the event that the
current command port operation is a write cycle. (As indicated by slot 1, bit 19).
Bit (19:4)
Control register write data (stuffed with 0s if current operation is
a read)
Reserved (stuffed with 0s)
Bit (3:0)
If the current command port operation is a read then the entire time slot must be stuffed with 0s by
the AC
’
97 controller.
SLOT 3: PCM PLAYBACK LEFT CHANNEL
Audio output frame slot 3 is the composite digital audio left playback stream. In a typical Games
Compatible PC this slot is composed of standard PCM (.wav) output samples digitally mixed (on the
AC
’
97 controller or host processor) with music synthesis output samples. If a sample stream of
resolution less than 20-bits is transferred, the AC
’
97 controller must stuff all trailing non-valid bit
positions within this time slot with 0s.
SLOT 4: PCM PLAYBACK RIGHT CHANNEL
Audio output frame slot 4 is the composite digital audio right playback stream. In a typical Games
Compatible PC this slot is composed of standard PCM (.wav) output samples digitally mixed (on the
AC
’
97 controller or host processor) with music synthesis output samples.
If a sample stream of resolution less than 20-bits is transferred, the AC
’
97 controller must stuff all
trailing non-valid bit positions within this time slot with 0s.
SLOT 5: OPTIONAL MODEM LINE CODEC
Audio output frame slot 5 contains the MSB justified modem DAC input data. This optional AC
’
97
feature is not supported in the WM9703, and if data is written to this location it is ignored. This may
be determined by the AC
’
97 controller interrogating the WM9703 Vendor ID registers.
SLOTS 6 TO 9: SURROUND SOUND DATA
Audio output frame slots 6 to 9 are used to send surround sound data. This data is mapped onto the
internal DACs depending on Codec ID, see Table 8.
SLOTS 10 AND 11: LINE2 AND HANDSET DAC
These data slots are not supported.
SLOT 12: GPIO CONTROL
These data slots are not supported.

Figure 15 AC-link Audio Input Frame
The audio input frame data streams correspond to the multiplexed bundles of all digital input data
targeting the AC
’
97 controller. As is the case for audio output frame, each AC-link audio input frame
consists of 12, 20-bit time slots.
Slot 0 is a special reserved time slot containing 16-bits, which are used for AC-link protocol
infrastructure.
