Tatsu-san,

Thank you for bringing this to our attention. Very likely ,it is bug in the GUI interface. We will investigate and getback.

Hello Tatsu-san,

We did confirm that it is bug in the "display of GUI" only. We will fix this issue in the future release. There is no defect in the actual device or firmware functionality.

The firmware functions as described in datasheet.

Once again , thank you for bring this issue to our attention.

Thanks and regards,

Vivek

Hi

Thank you

BUT

In my environment, the DLPC3478 device behavior and GUI display are the same.

Hello Tatsu-san,

Thank you for verifying it. We also investigated and reviewed the internal design documents. The following is the findings:

1. The information in datasheet is incorrect. The only rising edge of the trigger 2 should be delayed by Td2. The falling edge will not be affected. We wil update the datasheet to fix this error.

2. The GUI and firmware are correct. The operation is as per definition.

regards,

Vivek
