2. If the keys connected to X0.5, X0.3, X0.0, and X0.1 are pressed in the order shown in the
timing chart, the result 5,301 is stored in D0. The maximum value which can be stored in D0 is
9,999. If the value exceeds four digits, the first digit from the left overflows.
3. After the key connected to the X0.2 is pressed and before other keys are pressed, M12 is ON.
The same applies to other keys.
4. When a key connected to the input within the range between X0.0 and X0.9 is pressed, the
corresponding output within the range between M10 and M19 is ON.
5. When one of the keys is pressed, M20 is ON.
6. When the conditional contact M0 is switched OFF, the value which was stored in D0 is
unchanged. However, M10~M20 are switched OFF.
