7-13. Set modify-read
This instruction stops the automatic increment of the column address by the read display data instruction,
but the column address is still increased by the write display data instruction. And it reduces the load of the
MPU when the data of a specific area is repeatedly changed during cursor blinking or others. This mode is
canceled by the reset modify-read instruction.
7-14. Reset modify-read
This instruction cancels the modify-read mode, and makes the column address return to its initial value just
before the set modify-read instruction is started.
