be used for sub-stream 0
6-channel decoder:
bit2 = ’1’: sub-stream 0 is decoded

Description:
This register is used in MPEG, DVD_LPCM or CDDA
modes; it is not supported in Dolby Digital.
In MPEG and DVD_LPCM modes, its register value
is extracted from the bitstream. When the emphasis
status changes (by setting bit DEM of the register),
an interrupt is generated. In CDDA mode, the register
value must be updated by the application.
The de-emphasis filter specified here is applied only
if bit DEM of the register is set.
