HI DaveD
Thank you answer.
Why, reason for customers focusing on reverse operation,
They are used to visually check the wiring abnormality of bits on the LSB side.
As shown in the "Screen Image" tab in the attachment,
The reverse operation is can see clearly abnormal on LSB side.
However, on account of the internal wiring in the ADV7513,
It was found that it becomes dark image even if the reverse operation.
And that can not be used for visually check the wiring abnormality.
Best Regards
