Question about ADV7180

I'd like to detect "IN_LOCK" early and detect "LOST_LOCK" late.

 

A video signal (NTSC M/J) is input.

I have set the value for CIL[2:0] to 7、the value for COL[2:0] to 7、the value for SRLS to 0.
IN_LOCK and LOST_LOCK were detected within 1 second.

I was thinking "LOST_LOCK" was detected in about 6 seconds, but it was detected in about 2 seconds.
IN_LOCK was detected within 1 second.

 

Isn't setting necessary to anything but address 0x51?

Or aren't there other ways?
