    How do I check the ROM/RAM size for each file of FR81S MCUs?



    You can check the ROM/RAM size of each using a list file of SOFTUNE.


    In the SOFTUNE Workbench, select the menu item Project > Setup Project > C/C++ Compiler. In the Setup Project dialog, go to the C/C++ Compiler tab, and select the Creates an assembly list file option. After compiling this setting, an assembly list will be created. Check the ROM/RAM size in this assembly list.
