2.2.4 Cross-Color Cancellation Demonstration Mode
By setting CCT (SUB:5Fh-bit[6]) in the I2C-bus interface, only chrominance signals can be displayed by fixing
the luminance signal level to 80h.
By setting DMCC (SUB:5Fh-bit[7]) in the I2C-bus interface, the cross-color cancellation function can be checked
as a demonstration mode by splitting the screen as shown in Figure F2-2-4.
