(19) LCD DRIVER CIRCUIT
This drive circuit generates four levels of LCD drive voltage. The circuit has 384 segment outputs
and 82 common outputs and outputs combined display data and FR signal.
Two of common outputs(COMI
0
,COMI
1
) are for pictograph marker display only. The common
drive circuit that has shift register and outputs common scan signals sequentially.
(20) DUMMY SEGMENT DRIVER CIRCUIT
Segment driver circuit has 6 dummy output ( SEGSA
0
~ SEGSA
3
, SEGSB
0
~ SEGSB
3
, SEGSC
0
~
SEGSC
3
) at each edge side. Normally, the segment driver output is generated by memorized
RAM data but there are no RAMs but registers for dummy segment driver. There are 8 bit registers
correspond to SEGSA
0
, SEGSB
0
, SEGSC
0
and drive LCD with same level to Y direction. ( SEGSA

are the same function. )

This circuit is effective at display of boundary or background display. The dummy segment
drivers do not depend on LREV polarity but ALLON and REV command for display
There are 4-byte registers for dummy segment driver, SEGSA

, If you want to access this register, please use DMY =”1” command.

There are the same rules at read out of dummy segment register as display RAM data read out
sequence. After address setting, the data of assigned address is shown directly after the end of
the read command, so pay attention that assigned data is available at 2nd timing step. In other
words, there needs 1 cycle dummy read after address set and write cycle.
1 cycle dummy read is necessary for after address setting and write cycle.
When access with DMY=”1”, X address is an effective value at address setting. There are 4-byte
and so 00
H
, 01
H
, 02
H
, 03
H
are effective at 8-bit mode and 00
H
, 01
H
are effective at 16-bit mode.
The access bears no relation to Y address setting.
When access with DMY=”1”, it is possible that the data is written into register by increment
operation.
