(10) STATUS FROM DSP MICOM
The status data from the DSP microprocessor is sequentially displayed in a hexadecimal number.
All signal processing before this menu is executed will be held.
[CPU/1]
<High Byte>
acmod: If it is 1000B or more with DTS 7.1 signal, the DSP block will be muted.
<Low Byte>
[Note]
IEC958: Standard to identify the PCM bit stream signal. Digital format error refers to a digital
signal with the sampling frequency undefined (neither 44.1k, 32k nor 48k). Since the
operation of each device cannot be assured at fs outside specifications, the sub-microproc-
essor handles this status as the forced analog mode (ignored even if decoding is OK from
the detection terminal level), and selects the signal from the analog input terminal. Since
the sub-microprocessor transmits 000B (analog) for STATUS#0 bits 4-6 to the main micro-
processor, the main microprocessor visually operates in the same way as with digital
unlocking.
[CPU/2]
<High Byte>
<Low Byte> Always “00”
[CHS/1/2] IEC958 channel status bits 00-31 available from DIR2
<CHS/1 Hi-byte> bits 00-07
<CHS/1 Lo-byte> bits 08-15
<CHS/1 Hi-byte> bits 16-23
<CHS/1 Lo-byte> bits 24-31
[VER/1/2] 4-byte ASCII code of sub CPU version data
[SUM1/2] Displays the check sum of sub microprocessor program area with ASCII 4 bytes in a hexadecimal number.
[BI0/1/2] Displays the bit stream information contained in Dolby Digital (AC-3)/DTS signal from the first byte.
[BI1-5/1/2] Displays the bit stream information contained in Dolby Digital (AC-3) signal from the fifth byte.
