Notes 1: Read value of bits 2 to 7 of the color code 2 is undefined.
2: For “not used” bits, the write value is read.
3: Do not use character code “0FF16,” “10016.”
4: Do not use character code “1F16,” “2016.”
5: Refer to Figure 12.11.24.
6: Only CDOSD mode, a dot which selects color pallet 0 or 8 is colored to the color pallet set by RC13 to RC16 of OSD RAM
in character units.
