● The system areas listed above and the areas not listed above are used by the system and are not available for users. If
data are written by a user, the performance of the high-speed counter module is not guaranteed.
● Buffer memory data in the high-speed counter module are initialized when the high-speed counter module is powered on
or the CPU module is reset. To save the necessary data, read/write the data by executing the FROM/DFRO/TO/DTO
instructions in the program or performing auto refresh to the device data.
