Value R/W Description
31 to 16 LD15 to LD0 All 0 R/W Left Data 15 to 0
Write the PCM playback left channel data to these bits.
The HAC then transmits the data to the codec on an on-
demand basis.
Read these bits to get the PCM record left channel data
from the codec.
15 to 0 RD15 to RD0 All 0 R/W Right Data 15 to 0
Write the PCM playback right channel data to these
bits. The HAC then transmits the data to the codec on
an on-demand basis.
Read these bits to get the PCM record right channel
data from the codec.
