No.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.
[STATUS 0]
<1st Byte>
acmod: If it is 1000B or more with DTS 7.1 signal, the DSP block will be muted.
<2nd Byte>
[Note]
<3rd Byte>
<4th Byte> Always “00”
[STATUS 1] IEC958 channel status bits 00-31 available from DIR2
<1st-byte> bits 00-07
<2nd-byte> bits 08-15
<3rd-byte> bits 16-23
<4th-byte> bits 24-31
[STATUS 2] 4-byte ASCII code of sub CPU version data
[STATUS 3] Displays the check sum of sub microprocessor program area with ASCII 4 bytes in a hexadecimal number.
[STATUS 4] Displays the bit stream information contained in AC-3/DTS signal from the first byte.
[STATUS 5-9] Displays the bit stream information contained in AC-3 signal from the first byte.

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-microprocessor 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
microprocessor, the main microprocessor visually operates in the same way as with digital unlocking.
