Power On
End of initialization
Send reset pulse to the RES pin.
(Recommended minimum reset pulse width is 10ms)
Waiting for 10usec
Command Input
1. Function set (000100X1X0)
2. Contrast control register setup
3. Power save (power save off; OSC on)
4.
Power control (turns on the internal regulator and turns on the
internal divider)
Command Input
5. RAM address set
Data Input
6. Data writing (RAM clear)
(DDRAM=20h, CG/ICONRAM=00h)
Command Input
7. Display control (turns on the display) (There is an auto mask
off period ~ 260ms)
NOTE:
At instructions 1-6, the minimum clock cycle
time is 650ns for PPI. For details, pls refer
to the SSD1800 datasheet “AC
Characteristics”.
At 5 and 6, the internal RAM should be
cleared.
To clear DDRAM, set address at 00h (first
DDRAM) and then write 20h (space
character code) 64times.
To clear CGRAM, set address at 40h (first
CGRAM) and then write 00h (null data) 64
times
To clear ICONRAM, set CONRAM address
at 00h (first ICONRAM) and then write 00h
(null data) 16 times
No delay between each Command/Data
input under ideal timing situation (No time
shift in any signals, refer to page 32 for
details)
