RIM1–0: Specify the RGB I/F mode when RGB interface is selected. Specifically, this setting specifies
the RGB interface mode when it is selected by the setting DM and RM bits. The setting must be made
before the display operation through external display interface. Do not make a setting during display.

Note 1) The instruction register setting is possible only through a system interface.
Note 2) Data transmission and input of DOTCLK in the 6-bit RGB interface mode should be executed by
RGB.
DM1–0:Specify the display operation mode. The interface through which display operation is executed is
selected with DM1-0 bits. This setting enables switching between internal clock operation and external
display interface. Switching within the external display interface modes (between RGB-I/F and VSYNC-
I/F) cannot be made.
