| 6 | 0 for 40x32, 1 for 80x32 |

| 4 | palette select (0 = first Tilemap palette, 1 = second) |
| 3-0 | Reserved, must be 0 |
Bits 7 & 6 enable the tilemap and select resolution.
Bit 5 changes the structure of the tilemap so that it contains only 8-bit tilemap-id entries instead of 16-bit tilemap-id and tile-attribute entries.
If 8-bit tilemap is selected, the tilemap contains only tile numbers and the attributes are taken from Default Tilemap Attribute Register ($6C).
Bit 4 selects one of two tilemap palettes used for final colour lookup.
