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.
Program example
In this program, word [unsigned]/bit string [16-bit] data stored in a device specified in
by "n" bits, and the obtained data is output to a device specified in
device specified in
