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 pro-

gram 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.

Trace Macro

A macro that will provide trace information from emulator data. Since this is a software

trace, the macro must be added to code, the code must be recompiled or reassembled,

and the target device must be programmed with this code before trace will work.

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.

Trigraphs

Three-character sequences, all starting with ??, that are defined by ISO C as

replacements for single characters.

Unassigned Section

A section which has not been assigned to a specific target memory block in the linker

command file. The linker must find a target memory block in which to allocate an

unassigned section.

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.

USB

Universal Serial Bus. An external peripheral interface standard for communication

between a computer and external peripherals over a cable using bi-serial transmission.

USB 1.0/1.1 supports data transfer rates of 12 Mbps. Also referred to as high-speed

USB, USB 2.0 supports data rates up to 480 Mbps.
