16-Bit C Compiler User’s Guide 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 A function that is invoked when an interrupt occurs. 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. Little Endianess A data ordering scheme for multibyte data whereby the least significant byte is stored at the lower addresses. Machine Code The representation of a computer program that is actually read and interpreted by the processor. A program in binary machine code consists of a sequence of machine instructions (possibly interspersed with data). The collection of all possible instructions for a particular processor is known as its “instruction set”. DS51284H-page 224 © 2008 Microchip Technology Inc.
Glossary Machine Language A set of instructions for a specific central processing unit, designed to be usable by a processor without being translated. Macro Macroinstruction. An instruction that represents a sequence of instructions in abbreviated form. Memory Models A representation of the memory available to the application. Microcontroller (MCU) A highly integrated chip that contains a CPU, RAM, program memory, I/O ports and timers. Mnemonics Text instructions that can be translated directly into machine code. Also referred to as Opcodes. MPLAB ASM30/LINK30/LIB30 Previous names for Microchip’s relocatable macro assembler, object linker and object archiver/librarian supporting 16-bit devices. MPLAB C17/C18/C30 Previous names for various C compilers from Microchip. MPLAB C17 supports PIC17CXXX devices, MPLAB C18 supports PIC18CXXX and PIC18FXXXX devices, and MPLAB C30 supports dsPIC30F/33F DSCs and PIC24H/F MCUs. MPLAB Language Tool for Device Microchip’s C compilers, assemblers and linkers for specifed devices. Select the type of language tool based on the device you will be using for your application, e.g., if you will be creating C code on a PIC18 MCU, select the MPLAB C Compiler for PIC18 MCUs. MPLAB IDE Microchip’s Integrated Development Environment. Object File A file containing machine code and possibly debug information. It may be immediately executable or it may be relocatable, requiring linking with other object files, (e.g., libraries, to produce a complete executable program). Opcodes Operational Codes. See Mnemonics. Operators Symbols, like the plus sign ‘+’ and the minus sign ‘-’, that are used when forming well-defined expressions. Each operator has an assigned precedence that is used to determine order of evaluation. PIC MCUs PIC microcontrollers (MCUs) refers to all Microchip microcontroller families. © 2008 Microchip Technology Inc. DS51284H-page 225
