25.3.4
HACPCML is a 32-bit read/write register used for accessing the left channel of the codec in
digital audio recording or stream playback. To transmit the PCM playback left channel data to the
codec, write the data to HACPCML. To receive the PCM record left channel data from the codec,
read HACPCML. The data is left justified when accommodating a codec with ADC/DAC
resolution of 20 bits or less.

Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Data 19 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.
