Palette Value (8 bit colour) Register

Number	TBRegisterNumber::$41
Readable	TBRegisterReadable::Yes
Writable	TBRegisterWritable::Yes
Short Description	ShortDesc::Use to set/read 8-bit colours of the ULANext palette.

Bits 7-0 = Eight bit colour for the palette index selected by the {{#ask: TBRegisterNumber::$40 }} ($40).

Format is RRRGGGBB - Note the lowest blue bit of colour (ninth bit) will be set to an OR between bit 1 and bit 0.

After the write, the palette index is auto-incremented to the next index, if the auto-increment is enabled at {{#ask: TBRegisterNumber::$43 }} ($43). And also the index of {{#ask: TBRegisterNumber::$44 }} ($44) is reset, so the next write there will be considered as first byte of colour.

Read does not auto-increment the index, and reads always the top 8 bits of colour from palette, to read the 9th bit of colour, use {{#ask: TBRegisterNumber::$44 }} ($44) in tandem with value from this register.

The modified palette remains until a Hard Reset.
