Import
Bring data into the MPLAB IDE from an outside source, such as from a hex file.
Initialized Data
Data which is defined with an initial value. In C,
int myVar=5;
defines a variable which will reside in an initialized data section.
Instruction Set
The collection of machine language instructions that a particular processor 
understands.
Instructions
A sequence of bits that tells a central processing unit to perform a particular operation 
and can contain data to be used in the operation.
Internal Linkage
A function or variable has internal linkage if it can not be accessed from outside the 
module in which it is defined.
International Organization for Standardization
An organization that sets standards in many businesses and technologies, including 
computing and communications. Also known as ISO.
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. Upon 
completion of the ISR, normal execution of the application resumes.
Interrupt Handler
A routine that processes special code when an interrupt occurs.
Interrupt Service Request (IRQ)
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 (ISR)
Language tools  A function that handles an interrupt.
MPLAB IDE – User-generated code that is entered when an interrupt occurs. The loca-
tion 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.
L
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.
