Instruction Descriptions
Key Scan Data Read
In the serial interface mode, the key scan data read instruction reads scan data in scan registers SCAN0 to
SCAN3. Following transfer of the start byte, scan data read operation starts from scan register SCAN0 and
proceeds in the order of SCAN1, SCAN2, and SCAN3. When data read from SCAN 0 to SCAN3 is
complete, the operation starts from SCAN0 again. For details, see the Key Scan Control section.

Clear Display
The clear display instruction writes space code 20H (character pattern for character code 20H must be a
blank pattern) into all DDRAM addresses. It then sets DDRAM address 0 into the address counter (AC). It
also sets I/D to 1 (increment mode) in the entry mode set instruction. Since the execution time of this
instruction is 85 clock cycles, do not transfer the next instruction during this time.

Return Home
The return home instruction sets DDRAM address 0 into the address counter. The DDRAM contents do not
change. The cursor or blinking goes to the top left of the display.
