FS3-0: Sampling Frequency Detection (Table 17)
PEM:
Pre-emphasis Detect (Table 18)
0 : OFF
1 : ON
This bit is made by encoding the channel status bits.
NPCM: Non-PCM Bit Stream Auto Detection
0 : No detect
1 : Detect
DTSCD: DTS-CD Bit Stream Auto Detect
0 : No detect
1 : Detect
DAT:
DAT Start ID Detect
0 : No detect
1 : Detect
When the category code shows DAT, “1” when the Start ID of DAT is detected. Reading 08H register
resets it.
DAT bit is initialized when 08H is read.
