4.5.3 Display Data RAM (DDRAM)
GB Character Code (16bit, A1A0h~F7FFh) could write into DDRAM for displaying the Simplified
Chinese Character (16x16 dots font). User Characters (16bit, 0000h or 0002h) defined by user that
stored in CGRAM could also be used. The display character should be on grid only.

Note:
*1. The mapping is based on Vertical Scroll Displacement Address=0.
*2. Another 8x4(Characters) Display Data RAM space is not showed. They could be displayed by adjusting the Vertical Scroll
Displacement Address value.
Standard ASCII code (8bit, 00h~7Fh) could write into DDRAM for displaying the Standard ASCII
Character (8x16 dots font). The display character should be on grid only, and two characters
should be written in each write operation.
