"Chip Revision" register of ADV7511 and ADV7511W.

Hello,

I have a question about "Chip Revision" of ADV7511 and ADV7511W.

The "Chip Revision" register(address:0x00) of ADV7511 is 0x14.
The same "Chip Revision" register of ADV7511W is 0x13.
These are described on each Programming Guide.

Question:
Does it mean ADV7511W is equal to one older revision of ADV7511?
Or
Is chip revision of ADV7511W same to the latest ADV7511(chip revision = 0x14), but you intentionally change the "Chip Revision" register's value in order to distinguish between ADV7511 and ADV7511W?
Which is correct?

I know ADV7511 and ADV7511W are the same die.
So I think the chip revision of ADV7511W is same to the latest ADV7511(chip revision = 0x14).
But I'd like to know which is correct clearly.

Thank you!
Best regards.
Tamu
