NOTE:
When an MPU program with checking the busy flag (DB7) is made, it must be necessary 1/2fosc is
necessary for executing the next instruction by the falling edge of the “E” signal after the busy flag (DB7)
goes to “Low”.

Clear all the display data by writing “20H” (space code) to all DDRAM address, and set DDRAM
address to “00H” into AC (address counter).
Return cursor to the original status, namely, bring the cursor to the left edge on the fist line of the
display.
Make the entry mode increment (I/D=“High”).
