In the reference text for the tile-related statements, there are multiple references to "tile set or tile map," as if they both refer to the same concept. These should be corrected to refer to the proper concept in each instance.
If I'm understanding correctly, a tile set is the collection of up to 256 8x8 bitmaps and an affiliated bitmap LUT, and you can have up to four file sets (0-3). A tile map is a rectangle of two-byte tile IDs (tile number and set number), a visibility status, and a rendering offset, and you can have up to four tile maps (0-3).
