LPCMA_FORCE_DWS
Downsampling 192 to 96KHz
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
new output frequency.
