Programming Notes and Examples
Issue Date: 01/01/30
Write one pixel to the top left corner of display memory.
If the S5U13503B00C evaluation board is used in indexed I/O mode, there are two video memory banks which begin at
D000:0000 (2 banks x 64K per bank; see the following note). If the base port address is 310h, then read from port address
312h. Next, write 0FFh to location D000:0000h; this will be seen as a white pixel at the top left corner of the display.
