3. Timing chart
1) When the ten keys are pressed in the order "[1] → [2] → [3]
→ [4]" shown in the figure, "2130" is stored in (D0).
When an input value is larger than "9999", it overflows from
the most significant digit.
(An input numeric value is stored in binary format in D0).
2) When X002 is pressed, M12 turns ON and remains ON until
another key is pressed. Other keys work in the same way.
In this way, M10 to M19 turn ON and OFF according to the
inputs X000 to X011.
3) When pressing a key, the key sensing output M20 is ON only
while it is pressed.
