It connects tuner, probably turns power on. I don't if it needed or not 
in your device. At least it is needed when used AF9015 reference design 
with MT2060 or MT2061 tuners.

Don't care this setting before you have got tuner attached. Tuner module 
will print message to log when it was attached. That's good indicator to 
see that communication to tuner works. After that you should try to find 
correct settings for all other things.

Can you take logs with vendor WHQL driver and sent for further analysis?
