No.10 STATUS INFORMATION FROM DSP
The status data from the DSP block is sequentially displayed in a hexadecimal number.
High
1 0. CPU / 1 0 0 0 0
1 0. CHS / 2 0 0 0 0
1 0. B I 1 / 1 0 0 0 0

[Note]
When acmod is beyond 1000B, it is DTS 7.1 signal. And the DSP block will be muted.
The acmod of DTS 2/0 is as 000B:1+1.

bit7 AC-3 DECODE OK
bit6 DTS DECODE OK

[Note]
IEC958: Standard to identify the PCM bit stream signal. Digital format error refers to a digital signal with the
sampling frequency undefined (neither 32k,44.1k,48k,64k,88.2k nor 96k). Since the operation of each device
cannot be assured at fs outside specifications, this status handled as the forced analog mode (ignored even if
decoding is OK from the detection terminal level), and the signals from the analog input terminal will be
selected. Bits 4-6 of "CPU/1" will be 000B (Analog), and the microcomputer operates in the same way as with
digital unlocking.

[BI0/1,/2] Displays the bit stream information contained in AC-3(DOLBY DIGITAL)/DTS Digital Surround signal from the first byte.
[BI1-5/1,/2] Displays the bit stream information contained in AC-3(DOLBY DIGITAL) signal from the first byte.
