erty settings. If you haven't clicked [Apply], you can use the [Revert Settings] button to discard the changes

[Edit Section] dialog box
Standard section User section
Use the upper part of the dialog box to set the location information on a section in an executable file.
[Section name]
Set a user section name (output section).
note
: Keep in mind the following conditions when entering a section name:
• A section name must begin with ".".
• Only single-byte alphanumeric characters and symbols, the "_" character, and "." are
valid for section names.
[Virtual map address]
Set a location (start address) in which the section should be located when executed. To locate the sec-
tion following another section, select the section immediately preceding name from the pull-down list.
To locate the section at the beginning of a device or apart from the preceding section, enter the address
of that location (in hexadecimal notation).
note
: When entering an address, use only 0–9 and A–F. Make sure that the address entered is
six characters or less. Otherwise, your entry will be interpreted as a section name, not an
address.
[LMA
≠
VMA]
Select this check box when the execution address (VMA) and stored address (LMA) of the section are
different as for variables with initial values (e.g.,
.data
section) and programs executed in RAM.
Leave unselected if the section is to be executed directly in its stored location, as in ROM.
