2.The VSYNCX, HSYNCX, and DOTCLK signals must be supplied during display period.

3.The reference clock to generate liquid crystal panel controlling signals in RGB interface operation is DOTCLK, not the internal clock generated from the internal oscillator.

4.When switching between the internal operation mode and the external display interface operation mode, follow the sequences below in setting instruction.

5.In RGB interface operation, front porch period continues after the end of frame period until next VSYNCX input is detected.

6.RGB and 80-system bus interfaces cannot be used simultaneously.

7.In RGB interface operation, RAM address AD16-0 is set in the address counter every frame on the falling edge of VSYNCX.
