Display data read (Read)
This command read the 8-bit data from the specified address of the display data RAM. Since the column address is
automatically incremented (by +1) after reading the data, the MPU can read display data from the display data
RAM continuously. Further, one dummy read operation is necessary immediately after setting the column data.
The display data cannot be read out when the serial interface is being used.

Read data
ADC Select (segment driver direction select) (Write)
Using this command it is possible to reverse the relationship of correspondence between the column address of the
display data RAM and the segment driver output. It is possible to reverse the sequence of the segment driver
output pin by the command.

Normal/reverse display mode (Write)
It is possible to toggle the display on and off condition without changing the contents of the display data RAM. In
this case, the contents of the display data RAM will be retained.

Display all-ON/OFF (Write)
Using this command, it is possible to forcibly turn ON all the dots in the display irrespective of the contents of the
display data RAM. In this case, the contents of the display data RAM will be retained.
This command is given priority over the Normal/reverse display mode command.

The power save mode will be entered into when the Display all-ON command is executed in the display OFF
condition.
Read-modify-write (Write)
This command is used in combination with the End command. When this command is issued once, the column
address is not changed when the Display data read command is issued, but is incremented (by +1) only when the
Display data write command is issued. This condition is maintained until the End command is issued. When the
End command is issued, the column address is restored to the address that was effective at the time the
Read-modify-write command was issued last. Using this function, it is possible to reduce the overhead on the
MPU when repeatedly changing the data in special display area such as a blinking cursor.
