*1: For more information on setting the latched area, see HWCONFIG in ISPSoft or Hardware Configuration in
DIADesigner.. Setting the latched area means the other areas are seen as non-latched areas. The range of latched
areas cannot exceed the device range. For example, setting M600–M7000 as latched areas makes M0–M5999 and
M7001–M8191 non-latched areas.
*2: Used for editing in ISPSoft/DIADesigner only.
