MPLAB SIM
Microchip’s simulator that works with MPLAB IDE in support of PICmicro MCU and
dsPIC DSC devices.
MPLIB™ Object Librarian
Microchip’s librarian that can work with MPLAB IDE. MPLIB librarian is an object librar-
ian for use with COFF object modules created using either MPASM assembler (mpasm
or mpasmwin v2.0) or MPLAB C17/C18 C compilers.
MPLINK™ Object Linker
MPLINK linker is an object linker for the Microchip MPASM assembler and the Micro-
chip MPLAB C17 or C18 C compilers. MPLINK linker also may be used with the Micro-
chip MPLIB librarian. MPLINK linker is designed to be used with MPLAB IDE, though
it does not have to be.
MRU
Most Recently Used. Refers to files and windows available to be selected from MPLAB
IDE main pull down menus.
Native Data Size
For Native trace, the size of the variable used in a Watch window must be of the same
size as the selected device’s data memory: bytes for PIC18 devices and words for
16-bit devices.
Nesting Depth
The maximum level to which macros can include other macros.
Node
MPLAB IDE project component.
Non Real Time
Refers to the processor at a breakpoint or executing single-step instructions or MPLAB
IDE being run in simulator mode.
Non-Volatile Storage
A storage device whose contents are preserved when its power is off.
NOP
No Operation. An instruction that has no effect when executed except to advance the
program counter.
Object Code
The machine code generated by an assembler or compiler.
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.
Object File Directives
Directives that are used only when creating an object file.
Off-Chip Memory
Off-chip memory refers to the memory selection option for the PIC17 or PIC18 device
where memory may reside on the target board, or where all program memory may be
supplied by the emulator. The Memory tab accessed from Options>Development
Mode provides the Off-Chip Memory selection dialog box.
