All segments ON / OFF
Forces the whole LCD points to be turned on regardless of the contents of the display data RAM.At this time, the
contents of the display data RAM are held. This instruction has priority over the Reverse Display ON / OFF instruction.

Set Read-Modify-Write
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.
