Notes 1: Read value of bits 3 to 7 of the color code 2 is undefined.
2: For “not used” bits, the write value is read.
3: Refer to Figure 2.16.24.
4: Only in CDOSD mode, a dot which selects color palette 0 is colored to the color palette set by RC13 to RC16 of
OSD RAM in character units. When the character size is 1.5TC 1H or 1.5TC 1/2H, however, set RCI3 to RC16
and RC17 of all characters (including the 3nth character) within the same block to the same value.
