Section 33 Audio Codec Interface (HAC)
33.3.4 PCM Left Channel Register (HACPCML)
HACPCML is a 32-bit read/write data 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 to accommodate a codec with ADC/DAC resolution of
20 bits or less.

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.
In 16-bit packed DMA mode, HACPCML is defined as follows:
