When this instruction is executed, cursor and blinking position moves to the left end of the
LCD. (In the case of 2-line or 4-line display mode, it moves to the left end of the first line.)
When display is being shifted, the display returns to its original position for both
horizontally and vertically.
ADC becomes "00" (hex.).
CR/C = H (Carriage return)
When this instruction is executed, cursor and blinking position moves to the left end of the
line on which the cursor and brink were positioned before execution of instruction.
If the display is being shifted when this instruction was executed, the cursor and blinking
position moves to the original position before it was shifted only concerning to the shift to
the right and left.
All bits other than line specifying bit of ADC will be reset to "0" (hex.).

12. Instruction Code
The instruction code is defined as the signal through which the MSM6262-04 is accessed by
the CPU. MSM6262-04 starts its operation upon receipt of the instruction code.
The internal processing operation starts with a timing that does not affect the LCD display,
so, the busy condition is longer than that of cycle time.
In the busy condition, MSM6262-04 does not execute any instruction other than the reading
of busy flag. Therefore, make certain that busy flag is set at "L" before inputting the instruc-
tion code.
(1) Display clear
When this instruction is executed, the LCD display is cleared.
When cursor display and/or character blink is being performed, their display position
moves to the left end of the LCD. (In the case of 2-line or 4-line display mode, it moves to
the left end of the first line.)
All of the DD RAM data becomes "20" (hex), while ADC data becomes "00" (hex.). If the
display is on a shifted position, it returns to the original position.
Data for underline is re-written as "L" and display turns off.
(2) Return
CR/C = L (Cursor home)
