Internal Inspection

1. DSP IF Check
When an error occurred, the inspection stops displaying [Er.11]-[Er.13] in the LED display.
2. DSP SDRAM Check
When "Data Error", the inspection stops displaying [Er.22] or [Er.23] in the LED display.
When "Address Error", the inspection stops displaying [Er.21] in the LED display.
3. CPU ROM Check
When "Checksum Error", the inspection stops displaying [Er.31] in the LED display.
Notice: When the start-up condition or the forwarding between CPU <-> DSP is NG,
KP3 cannot start the test mode, because after the forwarding the Boot code,
KP3 moves to the self check sequence (TEST MODE).
*USB check needs a special computer, so skip by [SAMPLE BANK A] + [TAP/RANGE]
when an error occurred in the inspection.
