I have some questions about I2C communication of ADV7611.
Question 1: When "98 FF 80 ; I2C reset" command is received, NACK is returned from AV7611. I think this is normal operation at I2C reset. Is this right?
Question 2: Are there any other I2C register settings which NACK is returned (ACK is not returned) except "98 FF 80 ; I2C reset"?
Thank you!Best regards.
I2C reset is the only write that will no ACK back.. The reset bit resets the I2c engine before it has a chance to ACK back.
