Hello,

 

I am facing an issue when the input signal format is changed from PAL to NTSC.

ADV7182 chip does not autodetecting when input signal format is changed from PAL to NTSC.

I am receiving the interrupt when changing format but input signal is not locked forever.

Please suggest me what went wrong or is this expected behavior?

Note: Changing format from NTSC to PAL is autodetected and working as expected.
