6. Write data
The 8-bit display data is written in the display data RAM. After writing the display data, the column address is
automatically incremented. When writing the successive display data after setting the first column address
using the column address set command, it is unnecessary to set the column address each time.
7. Read data
The 8-bit display data is read from the display data RAM. After reading the display data, the column address is
automatically incremented. When reading the successive display data after setting the first column address
using the column address set command, it is unnecessary to set the column address each time. For reading
display data just after the column address set, a dummy read is needed.
8. ADC select
Forward or reverse is selectable for the correspondence between the column address and the segment output
terminal of the display data RAM. When configuring an LCD panel with more than two ICs, it is possible to
reverse the segment output order from the MPU. Since the segment output terminals of an S-4525BA go from 0
to 60, the valid column address for the display data of the reverse select side IC is 13
H
to 4F
H
. Refer to the
correspondence between the display data RAM and the address in Figure 6.
D
0
D : “0”
Forward The column addresses 0
H
to 3C
H
correspond to the segment output terminals 0 to 60.
D : “1”
ReverseThe column addresses 13
H
to 4F
H
correspond to the segment output terminals 60 to 0.
9. Display all-lit ON/OFF
Display all-lit ON makes the display be entirely lit. All common outputs become selectable status. Segment
output is compelled to be all-lit output. The display RAM’s data, however does not change.
Through Display all-lit OFF, the screen returns to normal display operation.
When inputting the Display OFF command in the display all-lit ON status, it changes to Power save mode.
Refer to the Power save command.
10. Duty select
The duty for the LCD drive output is selected.
11. Read modify write
The read modify write command is valid when partly altering or rewriting the display data RAM, for example the
cursor indication, the blinking indication, etc. After inputting the Read modify write command, column address of
the display data RAM is incremented only when inputting the display data write command. In Read data
command, it is possible to rewrite the display data of the column address which is read, without increment of the
column address. Furthermore, when reading and writing of the display data is successively executed, the
successive address of the display data RAM is rewritten within the same page. A dummy read is needed when
reading the display data.
Read modify write command is valid until the End command is input. When inputting the End command, the
column address returns to the address before the Read modify command was input.
During the Read modify write command operation, all commands are usable except the Column address set
command.
12. End command
This command cancels Read modify write. The column address of the display data returns to the address
before Read modify write was executed.
