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 opearation 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
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:
When "1 → 2 → 3 → B → F" is input, numerical value "23BF" is stored in
"1" overflows when "F" is input.
