Explanation of function and operation
1. 16-bit operation (TKY)
stores 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 "9999", it overflows from the most significant digit.
- An input numeric value is stored in the binary format.
- When the ten keys are pressed in the order "[1]
→
[2]
→
[3]
→
[4]" in the figure shown on the next page,
"2130" is stored in
.
