Explanation of function and operation
This function converts double word [signed] data stored in a device specified in into word [signed] data,
and outputs the data obtained by conversion to a device specified in .
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different
from simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
Use global labels when specifying labels.
