STA310
Description:
This register controls the MLP downmix.
MLP_DRC
Dynamic range control
Address : 0x6A
Type: R/W
Software Reset: NC
Hardware Reset:: UND
Description:
When this register = 0x00, the dynamic range control
is disabled. When 0x01, the dynamic range control is
enabled and the DRC information in the MLP stream
is used.
MLP_FORCE_DWS
Address: 0x70
Type: R/W
Software Reset: NC
Hardware Reset: UND
Description:
This register selects whether downsampling is used
for input streams requiring sampling frequencies of
192KHz or 176.4KHz. When ’automatic’ is selected,
register is automatically updated to correspond to the
84/90
Downsampling 192 to 96kHz or 176.4 to 88.2kHz
