17.2.2.1 Viewing the code
When switching to the source mode from within the disassembly window, the source file relating to the current PC
address will be opened if available. Otherwise either the most recently open disassembly window source file will be re-
opened where possible or a prompt will be given to select a source file to be opened.
Any text-based files may be opened in the disassembly window and not just project source files. Any source file opened
in the disassembly window is read-only and cannot be edited; it is only intended for the viewing and debugging of
source files.
This view is only available when the module is downloaded.
