After the write, the palette index is auto-incremented to the next index, if the auto-increment is enabled at {{NextRegNo\|$43}}. And also the index of {{NextRegNo\|$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 {{NextRegNo\|$44}} in tandem with value from this register.
