15 External FX I/O Device – FNC 70 to FNC 79
15.2 FNC 71 – HKY / Hexadecimal Input
1) Input of a numeric value through keys 0 to 9:
- When an input value is larger than "9999", it overflows from the most significant digit.
- The numeric value input is stored to
- The numeric value input is stored to
in binary.
- The key sensing output
+7 turns ON when any key 0 to 9 is pressed.
2) Key pressing information for the keys A to F:
- Six devices starting from
corresponding to keys A through F turn ON.
- The key sensing output
+6 turns ON when any key A through F is pressed.
2. 32-bit operation (DHKY)
Signals [
to
+3] and [
to
+3] connected to the 16 key input (0 to F) are scanned.
When a key 0 to 9 is pressed, the corresponding numeric value is shifted into [
+1,
] from the least
significant byte, and
+7 turns ON.
When a key A to F is pressed, the corresponding key press information bit [
to
+5] turns ON. and
+6 turns ON.

Extension function
When M8167 is set to ON making the extension function valid, the numerical values for keys 0 to F are stored in
binary.
When the extension function is valid, the function and operation are the same except for the following.
binary.
When the extension function is valid, the function and operation are the same except for the following.
1. 16-bit operation (HKY)
Hexadecimal numerical value data input using keys 0 to F is shifted into
from the least significant byte.
1) Input of a numeric value using keys 0 to F:
- When the input value is larger than "FFFF", it overflows from the most significant digit.
- Example:
- Example:
When "1
→ 2 → 3 → B → F" is input, numerical value "23BF" is stored in
in binary.
"1" overflows when "F" is input.
