ST7528
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 microprocessor 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.
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.
