Downsampling filter
Address: 0x70
Type: R/W
Software Reset: NC
Hardware Reset: UND
Description:
This register controls the downsampling filter for the
LPCM video, LPCM audio modes. When decoding a
96kHz DVD-LPCM stream, it might be necessary to
downsample the stream to 48kHz .
9.15 Bass redirection registers
VOLUME0
Volume of first channel
Address: 0x4E
Type: RWS
Software Reset: 0
Hardware Reset: UND
Description:
This register reads or writes the attenuation that is
applied to the channel selected by CHAN_IDX. The
volume of the left channel can be set up with a 0.5dB
step.
62/90
If CHAN_IDX = 0, then VOLUME0 can be
written with the attenuation that will be applied
to Left channel.
If CHAN_IDX = 1, then VOLUME0 can be
written with the attenuation that will be applied
to Center channel.

Volume of second channel
Address: 0x63
Type: RWS
Software Reset: 0
Hardware Reset: UND
Description:
This register reads or writes the attenuation that is
applied to the channel selected by CHAN_IDX. The
volume of the right channel can be set up with a
0.5dB step.
If CHAN_IDX = 2, then VOLUME0 can be
written with the attenuation that will be applied
to Left Surround channel.
If CHAN_IDX = 5, then reading VOLUME0
provides the attenuation that is applied to Left
channel.
If CHAN_IDX = 6, then reading VOLUME0
provides the attenuation that is applied to
Center channel.
If CHAN_IDX = 7, then reading VOLUME0
provides the attenuation that is applied to Left
Surround channel.
Other values of CHAN_IDX are reserved.
If CHAN_IDX = 0, then VOLUME1 can be
written with the attenuation that will be applied
to Right channel.
If CHAN_IDX = 1, then VOLUME1 can be
written with the attenuation that will be applied
to Subwoofer channel.
If CHAN_IDX = 2, then VOLUME1 can be
written with the attenuation that will be applied
to Right Surround channel.
If CHAN_IDX = 5, then reading VOLUME1
provides the attenuation that is applied to Right
channel.
If CHAN_IDX = 6, then reading VOLUME1
provides the attenuation that is applied to
Subwoofer channel.
If CHAN_IDX = 7, then reading VOLUME1
provides the attenuation that is applied to Right
Surround channel.
Other values of CHAN_IDX are reserved.
