11.1.4 Creating Special Sections
The linker constructs a special input section named .dinit to support initialized data. Section.dinit is an initialization template that is interpreted by
the C run-time library. For more information about initialized data, see 11.5 Initialized Data.
If the application has not defined a default interrupt handler, the linker
will create one automatically in a special input section named .isr. Unused slots in the interrupt vector tables are populated with the
address of this function. For more information on the default interrupt handler, see
section 11.9 Interrupt Vector Tables [DD].
