g)Slot7 S/PDIF output data channel1 (16bits)
In case of selecting slot7 and 8 of SDATA_OUT for S/PDIF output data , the AK4545 uses data format in the slot7 for
channel1 of S/PDIF output data. This data format is MSB first. Data format is 16bits 2’s complement. AC’97
controller should stuff bit3-0 with “0”. If valid bit (slot7) in the slot 0 is invalid ( “0”), the AK4545 interprets the data
as all “0”.

h)Slot8 S/PDIF output data channel2 (16bits)
In case of selecting slot7 and 8 of SDATA_OUT for S/PDIF output data , the AK4545 uses data format in the slot8 for
channel2 of S/PDIF output data. This data format is MSB first. Data format is 16bits 2’s complement. AC’97
controller should stuff bit3-0 with “0”. If valid bit (slot8) in the slot 0 is invalid ( “0”), the AK4545 interprets the data
as all “0”.
