ADV7182 IRQ line pulled low by default

After resetting the ADV chip then turning ON by writing 0x00 into power management register, the IRQ line is pulled low immediately.

I didn't do any configuration yet, how the IRQ line is pulled low after turning ON?

I can see the "interrupt status 1" register is  set for all.

Which means, the ADV chip is broken or something else?

Even if I do the proper configuration, IRQ line is in low always. No input is provided.

Please help.
