Note 1) the instruction register setting can be made only through a system interface.
Note 2) The RGB-I/F and VSYNC-I/F are not compatible with each other.
Note 3) Do not change the setting for RGB-I/F mode (RIM-0) while RGB I/F is in operation.
Note 4) See the “External Display Interface” section for the transition flow of each operation mode.
Note 5) In the RGB-I/F and VSYNC-I/F modes, write data in the high speed write mode (HWM = 1).
