Glossary
International Organization for Standardization
An organization that sets standards in many businesses and technologies, including
computing and communications.
Interrupt
A signal to the CPU that suspends the execution of a running application and transfers
control to an Interrupt Service Routine (ISR) so that the event may be processed.
Interrupt Handler
A routine that processes special code when an interrupt occurs.
Interrupt Request
An event which causes the processor to temporarily suspend normal instruction
execution and to start executing an interrupt handler routine. Some processors have
several interrupt request events allowing different priority interrupts.
Interrupt Service Routine
User-generated code that is entered when an interrupt occurs. The location of the code
in program memory will usually depend on the type of interrupt that has occurred.
IRQ

Linker
A language tool that combines object files and libraries to create executable code,
resolving references from one module to another.
Linker Script Files
Linker script files are the command files of a linker. They define linker options and
describe available memory on the target platform.
Listing Directives
Listing directives are those directives that control the assembler listing file format. They
allow the specification of titles, pagination and other listing control.
Listing File
A listing file is an ASCII text file that shows the machine code generated for each C
source statement, assembly instruction, assembler directive, or macro encountered in
a source file.
Local Label
A local label is one that is defined inside a macro with the LOCAL directive. These
labels are particular to a given instance of a macro’s instantiation. In other words, the
symbols and labels that are declared as local are no longer accessible after the ENDM
macro is encountered.
