AO8 - IPC4, LED2 test
This test checks around the AO8 - IPC4 and LED2.
When other checks are necessary, the pop-up dialog box is displayed to ask the inspector
to select OK or NG and the system stands by until the inspector makes a selection.
The current status is displayed in real time and the inspector looks at the behavior of the
system and judges it OK/NG.
Detects PLL for valid detection (IC301 of IFC3 sheet).
Same as up till here

AO8 - IPC2 test
This test checks around the AO8 - IPC2. Ports A and B are both checked, so the same procedure is carried out in 5-1 for Port A and
in 5-2 for Port B.
Before starting these items, refer to page 23 and set all settings for MSB/LSB,2CH/4CH lines to off.
NG sample
Please refer to page 24 for NG charts.
