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”.

Bit 1:0

“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”.
