08–46H: overlay color registers
Set colors which overlay displays.
When input mode is YCbCr, overlay colors are set in YCbCr format.
YG0–YG15 register: Sets luminance level as 8-bit unsigned integer
Black level is 0; setting value must be under 240.
B0–B15 register:
Sets Cb signal at 8-bit 2s complement signed integer
R0–R15 register:
Sets Cr signal at 8-bit 2s complement signed integer
When input mode is RGB, overlay colors are set in RGB format. In this case, black level is 0. When IMOD0 is
0, the setting value must be less than 240. When IMOD0 is 1, there is no limitation on value setting.
YG0–YG15 register: Sets G signal level at 8-bit unsigned integer
B0–B15 register:
Sets B signal level at 8-bit unsigned integer
R0–R15 register:
Sets R signal level at 8-bit unsigned integer
