*1 Since the QJ71E71-100 treats application data in Little Endian format, the byte-order needs to be
swapped.
Since the QSCPU does not support the SWAP instruction, the upper and lower bytes are swapped in
the following way.
1) Store the swap-target data into the areas (M1000 to M1015).
2) Move the lower-byte data in the areas (M1000 to M1007) to the other areas (M1016 to M1023).
3) Return the data in the areas (M1008 to M1023) to the original device.
(3) Monitoring data with a programming tool
The read input data sets can be monitored using the device monitor function of a
programming tool. For the execution results of the program, refer to Section
8.2.2 (3).
