Hello.

 

I have a question about reset of ADV7181D.

 

There is a description about reset pin on HW manual "5.2 Reset Control" P.10 as follows:
"System Reset Input, Active Low. A minimum low reset pulse width of 5 ms is required to reset the ADV7181D circuitry."

 

Also, there is a description on HW manual "5.2 Reset Control" P.30 as follows:
"Executing a software reset takes approximately 2 ms. However, it is recommended to wait 5ms before any further I2C writes are performed."

 

Question:
When we use reset pin, can we write registers via I2C immediately after reset pin is released?
or
Should we wait 5ms for writing registers via I2C after reset pin is released?

 

Thank you!
Best regards.
