SED1565 Series
ADC Select (Segment Driver Direction Select)
This command can reverse the correspondence between the display RAM data column address and the segment driver
output. Thus, sequence of the segment driver output pins may be reversed by the command. See the column address
circuit (page 1–20) for the detail. Increment of the column address (by “1”) accompanying the reading or writing the
display data is done according to the column address indicated in Figure 4.
Display Normal/Reverse
This command can reverse the lit and unlit display without overwriting the contents of the display data RAM. When
this is done the display data RAM contents are maintained.
Display All Points ON/OFF
This command makes it possible to force all display points ON regardless of the content of the display data RAM. The
contents of the display data RAM are maintained when this is done. This command takes priority over the display
normal/reverse command.
When the display is in an OFF mode, executing the display all points ON command will place the display in power save
mode. For details, see the (20) Power Save section.
LCD Bias Set
This command selects the voltage bias ratio required for the liquid crystal display.
Read/Modify/Write
This command is used paired with the “END” command. Once this command has been input, the display data read
command does not change the column address, but only the display data write command increments (+1) the column
address. This mode is maintained until the END command is input. When the END command is input, the column
address returns to the address it was at when the read/modify/write command was entered. This function makes it
possible to reduce the load on the MPU when there are repeating data changes in a specified display region, such as when
there is a blanking cursor.
* Even in read/modify/write mode, other commands aside from display data read/write commands can also be used.
