Explanation of function and operation
This function converts word [signed] data stored in a device specified in
into bit data, and outputs the
data obtained by conversion to a device specified in
.
When the input value is "0", this function outputs "FALSE".
When the input value is any value other than "0", this function outputs "TRUE".
