Section 33 Audio Codec Interface (HAC)
33.3.5 PCM Right Channel Register (HACPCMR)
HACPCMR is a 32-bit read/write register used for accessing the right channel of the codec in
digital audio recording or stream playback. To transmit the PCM playback right channel data to
the codec, write the data to HACPCMR. To receive the PCM record right channel data from the
codec, read HACPCMR. The data is left justified to accommodate a codec with ADC/DAC
resolution of 20-bit or less.

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.
