69000 Databook
Color Select Register
These are the 2 upper-most of the 8 bits that are used to map either text attributes or pixel
color input values (for modes that use 16 colors) to the 256 possible colors contained in the
palette. These 2 bits are common to all 16 sets of bits P5 through P0 that are individually
supplied by Palette Registers 0-F (AR00-AR0F).
These 2 bits can be used as an alternate version of palette bits P5 and P4. Unlike the P5
and P4 bits that are individually supplied by Palette Registers 0-F (AR00-AR0F), these 2
alternate palette bits are common to all 16 of Palette Registers. Bit 7 of the Mode Control
Register (AR10) is used to select between the use of either the P5 and P4 bits that are
individually supplied by the 16 Palette Registers or these 2 alternate palette bits.
