System Window Control
The system window control is located in the upper left corner of windows and some dia-
logs. 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 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.
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.
