ADV7511 EDID Memory address

Hi, I'm beginner using ADV7511.

 

I have a question.

 

According to datasheet, EDID is done by the following order.

 

HPD interrupt active --> Power Up --> Wait for EDID Ready Interrupt --> Read EDID data from I2C Address.

 

And 0x43 means the address of EDID Memory.

 

This is my problem.

 

When I do I2c Configuration, the value of 0x43 is firstly 0x7E.

 

But when I read the value continuously, its value changes to 0x14 from 0x7E.

 

Could the value of 0x43 changed automatically?
