Hello

What is the expected value in the 0x2B register?

Per datasheet the register is reserved, but during a failure analysis we are seen that the suspected part has a Value of 10 and the good parts have a Value of 8.

This reserved register how could be changed?

Thanks

Hello,

When you say value of 10 or 8 it is in decimal, correct?

Hi Juan,

This is just a debug register which doesn't do much. Can you please send me a full register dump of a good vs bad run? Need to see if any other registers are giving any clue on what is happening here.

Can you explain what error you are seeing or issue?

Hello

I will request the file with the complete registers, it is the summary.

The impact on the product is not image display.
