TAS3251: Level Meter output register address

Tool/software:

There is mention of the the "Level Meter" in the datasheet in sections 7.5.1 and 7.5.2.10 (screenshots attached)

Yet, I don't see the actual register addresses where I can:

1. read the level meter.  
2. set it's alpha value.

Could you provide the addresses to those locations?

Thanks,
