Symbol
A symbol is a general purpose mechanism for describing the various pieces which
comprise a program. These pieces include function names, variable names, section
names, file names, struct/enum/union tag names, etc. Symbols in MPLAB IDE refer
mainly to variable names, function names and assembly labels. The value of a symbol
after linking is its value in memory.
System Window Control
The system window control is located in the upper left corner of windows and some
dialogs. Clicking on this control usually pops up a menu that has the items “Minimize,”
“Maximize” and “Close.”
Target
Refers to user hardware.
Target Application
Software residing on the target board.
Target Board
The circuitry and programmable device that makes up the target application.
Target Processor
The microcontroller device on the target application board.
Template
Lines of text that you build for inserting into your files at a later time. The MPLAB Editor
stores templates in template files.
Tool Bar
A row or column of icons that you can click on to execute MPLAB IDE functions.
Trace
An emulator or simulator function that logs program execution. The emulator logs
program execution into its trace buffer which is uploaded to MPLAB IDE’s trace
window.
Trace Memory
Trace memory contained within the emulator. Trace memory is sometimes called the
trace buffer.
Trigger Output
Trigger output refers to an emulator output signal that can be generated at any address
or address range and is independent of the trace and breakpoint settings. Any number
of trigger output points can be set.
Uninitialized Data
Data which is defined without an initial value. In C,
int myVar;
defines a variable which will reside in an uninitialized data section.
Upload
The Upload function transfers data from a tool, such as an emulator or programmer, to
the host PC or from the target board to the emulator.
Warning
An alert that is provided to warn you of a situation that would cause physical damage
to a device, software file, or equipment.
