depending on the target CPU module and memory area.
This unit is called a file size unit.
(a) File size units classified by memory areas
The following table indicates the file size units classified by the target CPU
modules and memory areas.
* 1 : The file size unit of the Flash card applies to the case where files are written to the Flash card by
