Basement wall masonry units core filling required?

I live in Tennessee wherein I have heard that any wall with is 8 courses/rows of block or more must be core-filled, i.e. grouted. Is this correct?

What are the building code requirements that determine when core filling of basement masonry unit constructed walls is required?

If there is a nice layman readable table somewhere in a publicly available standard, I would greatly appreciate guidance on how to get to it.
