5.8. Display Data RAM (DD RAM)
Sunplus Technology Co., Ltd.
Proprietary & Confidential

FEB. 15, 2005
Version: 1.7
The DD RAM stores display data and its RAM size is 80 bytes.
The area in DD RAM that is not used for display can be used as a
general data RAM. Its address is set in the address counter.
There are the relations between the display data RAM
s address
and the LCD
s position shown belows.

5.9. Timing Generation Circuit
The timing generation circuit can generate needed timing signals
to the internal circuits. To prevent the internal timing interface,
the MPU access timing and the RAM access timing are separately
generated.
5.10. LCD Driver Circuit
There are 16 commons x 80 segments signal drivers in the LCD
driver circuit. When a program specifies the character fonts and
line numbers, the corresponding common signals will output drive
waveforms and the others still output unselected waveforms.
5.11. Character Generator ROM (CG ROM)
Using 8-bit character code, the character generator ROM
generates 5 x 8 dot or 5 x 10 dot character patterns. It also can
generate 192 5 x 8 dot character patterns and 64 5 x 10 dot
character patterns.
5.12. Character Generator RAM (CG RAM)
Using the programs, users can easily change the character
patterns in the character generator RAM. It can be written with 5
x 8 dots, 8 character patterns or written with 5 x 10 dots, 4
character patterns.
