About scripts file of AD9984A

There are some questions in your scripts file of AD9984A.


1. RO(read only) registers

According to your scripts file(AD9984A-VER.1.0c.txt), it seems to write to RO registers(0x00, 24, 25, 26, 27, 2A, 2B).

Should we write significant value to RO registers?


2. Address 0x2D

Datasheet shows that 0x2D must  be written to 0xE8 for proper operation.

But in your scripts file, 0x2D is written to 0x08.

Which is correct?


3. Address 0x2E

Datasheet shows that 0x2E must  be written to 0xE0 for proper operation.

But in your scripts file, 0x2E is written to 0x20.

Which is correct?


4. Address  0x2F-0x33, 0x35, 0x37-0x3B, 0x3D, 0x3E

According to your scripts file, above registers are written to significant value in case of "75MHz 70Hz XGA" and "65MHZ 60Hz XGA".

Should we do that?


Thank you for your cooperation in advance.


Best regards.
