(11) Read modify write
This command is used paired with End command. Once this command is issued, the column address is not incremented
by Display data read command, but is incremented by Display data write command. This mode is maintained until End
command is issued. When End command is issued, the column address returns to the address it was at when Read modify
write command was issued. This function makes it possible to reduce the MPU load when there are the data to change
repeatedly in a specified display region, such as blinking cursor.
Rev. 1.1a
*When End command is issued, only column address returns to the address it was at when Read modify write
*Even if Read modify write mode, other commands besides Display data read/write can also be used. However,
command was issued, but page address does not return. Consequently, Read modify Write mode cannot be used
over pages.
Column address set command cannot be used.
