Link
The process of combining object files and libraries to create executable code.
This operation is performed by a linker.
Linker
A language tool that combines object files and libraries to create executable
code. Linking is performed by Microchip’s linker, MPLINK.
Linker Script Files
Linker script files are the command files of MPLINK (.LKR). They define linker
options and describe available memory on the target platform.
Listing Directives
Listing directives are those directives that control the MPASM 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, MPASM 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.
Logic Probes
Up to 14 logic probes can be connected to some Microchip emulators. The
logic probes provide external trace inputs, trigger output signal, +5V and a
common ground.
Machine Code
Either object or executable code.
Macro
A collection of assembler instructions that are included in the assembly code
when the macro name is encountered in the source code. Macros must be
defined before they are used; forward references to macros are not allowed.
All statements following a MACRO directive and prior to an ENDM directive are
part of the macro definition. Labels used within the macro must be local to the
macro so the macro can be called repetitively.
Macro Directives
Directives that control the execution and data allocation within macro body
definitions.
