7-6-4. PIC_SDIO
[Contents]
Inspect the signal routes of digital audio between
DSP#4,5(IC401, IC501) and PIC(IC651),SRC(IC653). And
inspect connection between CPU(IC905) and SRC(IC653).
[Procedure]

In the case of PASS, "PASS: PIC_SDIO".
In the case of FAIL, the contents of failure are returned like
"FAIL: SDIO BYPASS READY".

7-7-1. AIN_AOUT
* Implemented in the MAINCOM circuit board test
[Contents]
Inspect the connections of CN701, CN702, CN703, CN704,
CN705 and each DSP by the loop back test of analog input/
output.
Specifi cally, it is determined by outputting the built-in
oscillator from each analog terminal, and measuring the
signal level returned to the analog input with DSP.
[Procedure]
Connect the following inputs and outputs by cables in
advance.
OMNI OUT 1 – > INPUT 1,
OMNI OUT 8 – > INPUT16,
OMNI OUT 9 – > INPUT17 (Used in TF5 or TF3),
OMNI OUT16 – > INPUT32 (Used in TF5),
PHONES L OUT – > ST IN 1L,
PHONES R OUT – > ST IN 2R
* Set PHONE LEVEL to MAX.
