Hello all,

 

Please let me know about I2C of ADV7611.

 

NACK is returned  when IO, Address 0xFF[7]=1 MAIN_RESET is written.
(please refer to attachnment)

Above is not done at  the other register.

 

HARDWARE USER'S GUIDE (UG-180) describes that read/write through I2C is done after 5ms from reset by input pin.
But, there is not any description about MAIN_RESET.

Question
1    Pleaes let me know the theory of operation which returns NACK immediately after MAIN_RESET 1:Applies main I2C reset

2   If there is any document  about return of NACK , please give me it.

 

Regards,
