d)Slot3 PCM Playback Left Channel (18bits)
In the case of codec ID1:codec ID0=0:0 or 0:1, the AK4544A uses the playback(DAC) data format in slot3 for left
channel.
Playback data format is MSB first. Data format is 18bits 2’s complement. AC’97 controller should stuff bit1-0 with
“0”. If valid bit (slot3) in the slot 0 is invalid (“0”), the AK4544A interprets the data as all “0”.

e)Slot4 PCM Playback Right Channel (18bits)
In the case of codec ID1:codec ID0=0:0 or 0:1, the AK4544A uses the playback(DAC) data format in the slot4 for right
channel. Playback data format is MSB first. Data format is 18bits 2’s complement. AC’97 controller should stuff
bit1-0 with “0”. If valid bit (slot 4) in the slot 0 is invalid (“0”), the AK4544A interprets the data as all “0”.

f)Slot5 Not implemented in the AK4544A
The AK4544A ignores this data slot.
g)Slot6 PCM Playback Left Channel (18bits)
In case of codec ID1:codec ID0=1:1, the AK4544A uses playback(DAC) data format in the slot 6 for left channel.
Playback data format is MSB first. Data format is18bits 2’s complement. AC’97 controller should stuff bit1-0 with
“0”. If valid bit (slot6) in the slot 0 is invalid (“0”), the AK4544A interprets the data as all “0”.

h)Slot7 PCM Playback Left Channel (18bits)
In case of codec ID1:codec ID0=1:0, the AK4544A uses playback(DAC) data format in the slot7 for left channel.
Playback data format is MSB first. Data format is18bits 2’s complement. AC’97 controller should stuff bit1-0 with
“0”. If valid bit (slot7) in the slot 0 is invalid (“0”), the AK4544A interprets the data as all “0”.

i)Slot8 PCM Playback Right Channel (18bits)
In case of codec ID1:codec ID0=1:0, the AK4544A uses playback(DAC) data format in the slot8 for right channel.
Playback data format is MSB first. Data format is 18bits 2’s complement. AC’97 controller should stuff bit1-0 with
“0”. If valid bit (slot8) in the slot 0 is invalid (“0”), the AK4544A interprets the data as all “0”.

j)Slot9 PCM Playback Right Channel (18bits)
In case of codec ID1:codec ID0=1:1, the AK4544A uses playback(DAC) data format in the slot 9 for right channel.
Playback data format is MSB first. Data format is 18bits 2’s complement. AC’97 controller should stuff bit1-0 with
“0”. If valid bit (slot9) in the slot 0 is invalid (“0”), the AK4544A interprets the data as all “0”.

k)Slot10-12 Not implemented in the AK4544A
The AK4544A ignores these data slots.
