Set the division of OSC clock for internal operation from
OSC1 input pin.
When reset,OSCC=000,OSC1 clock doesn't divide.
Don't set except left table.
Control the displaying ON/OFF of LCD.
When reset,DISP=0,set display OFF.

potential).
This function is prepared for controlling the voltage of LCD.
When the power supply is ON after finish each register setting ,LCDE="1",supply
voltage of LCD. Conversely for setting power supply OFF,first LCDE="0",the
voltage of LCD is OFF. Therefore enable to prevent LCD from being unusual
voltage as DC.
This function use for satisfy the need of LCD.
(2-2) Horizontal display characters number register [R2]
Note: Definition of the number of display characters
The number of display characters means data which is corresponding with 1 byte of VRAM.
In case of binary,1 bit of VRAM corresponds to 1 dot of display,then 1 character means 8 dots of display.
