Default Tilemap Attribute Register

Number	TBRegisterNumber::$6C
Readable	TBRegisterReadable::Yes
Writable	TBRegisterWritable::Yes
Short Description	ShortDesc::Default tile attribute for 8-bit only maps.

Bit	Function
7-4	Palette Offset
3	X mirror
2	Y mirror
1	Rotate
0	If in 512-tile-mode: bit 8 of tile-id else draw priority: 1 = ULA over tilemap, 0 = tilemap over ULA

This attribute is used for all tiles if bit 5 of {{#ask: TBRegisterNumber::$6B }} ($6B) is set.

When bit 1 of {{#ask: TBRegisterNumber::$6B }} ($6B) is set, the bit 0 of tile attribute works as ninth bit of tile-id (allowing 512 tiles in total), and the priority of layers is then "ULA over tilemap" as default.
