Hardware Manual
2. 32-bit operation (DTKY)
[
+1,
] store a numeric value input from
to
+9 connected to the ten keys. Output
informations for key pressing and key sensing are output to
to
+10.
1) Input numeric value [
]
- When an input value is larger than "99,999,999", it overflows from the most significant digit.
- An input numeric value is stored in the binary format.
2) Key pressing information [
to
+10]
- For the key pressing information,
to
+9 turn ON or OFF according to the pressed keys.
- For the key sensing output,
+10 turns ON when either key is pressed.
For the ten-key connection example and key pressing information, refer to the 16-bit operation (TKY) shown
above.
Cautions
1. When two or more keys are pressed at the same time
In such a case, only the first key pressed is valid.
2. When the command contact turns OFF
Though the contents of
do not change, all of
to
+10 turn OFF.
