Interrupt Request
An event which causes the processor to temporarily suspend normal instruction exe-
cution and to start executing an interrupt handler routine. Some processors have
several interrupt request events allowing different priority interrupts.
Interrupt Service Routine
ALU30, C18, C30 – A function that handles an interrupt.
IDE – 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.
Interrupt Vector
Address of an interrupt service routine or interrupt handler.
IRQ
See Interrupt Request.
ISO
See International Organization for Standardization.
ISR
See Interrupt Service Routine.
L-value
An expression that refers to an object that can be examined and/or modified. An l-value
expression is used on the left-hand side of an assignment.
Latency
The time between an event and its response.
Librarian
See Archiver.
Library
See Archive.
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.
Little Endian
A data ordering scheme for multi-byte data whereby the least significant byte is stored
at the lower addresses.
