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.

This command releases the read-modify-write mode and restores the column address to the value at the beginning

of the mode.

Reset (Write)

This command initializes the display start line number, column address, page address, common output state,

voltage V1 adjustment internal resistor ratio, electronic potentiometer function, and the static indicator function,

and also releases the read-modify-write mode or the test mode. This command does not affect the contents of the

display data RAM.

The reset operation is made after issuing the reset command.

The initialization after switching on the power is carried out by the reset signal input to the RES pin.
