One-to-One Project-Workspace Model
The most common configuration for application development in MPLAB IDE to is have
one project in one workspace. Select Configure>Settings
, Projects tab and check “Use
one-to-one project-workspace model”.
Opcodes
Operational Codes. See Mnemonics.
Operators
Symbols, like the plus sign ‘+’ and the minus sign ‘-’, that are used when forming
well-defined expressions. Each operator has an assigned precedence that is used to
determine order of evaluation.
OTP
One Time Programmable. EPROM devices that are not in windowed packages. Since
EPROM needs ultraviolet light to erase its memory, only windowed devices are eras-
able.
Pass Counter
A counter that decrements each time an event (such as the execution of an instruction
at a particular address) occurs. When the pass count value reaches zero, the event is
satisfied. You can assign the Pass Counter to break and trace logic, and to any
sequential event in the complex trigger dialog.
PC
Personal Computer or Program Counter.
PC Host
Any PC running a supported Windows operating system.
PICmicro MCUs
PICmicro microcontrollers (MCUs) refers to all Microchip microcontroller families.
PICSTART Plus
A developmental device programmer from Microchip. Programs 8-, 14-, 28-, and 40-pin
PICmicro microcontrollers. Must be used with MPLAB IDE software.
Plugins
The MPLAB IDE has both built-in components and plug-in modules to configure the
system for a variety of software and hardware tools. Several plug-in tools may be found
under the Tools menu.
Pod
MPLAB REAL ICE system: The box that contains the emulation control circuitry for the
ICE device on the header or target board. An ICE device can be a production device
with built-in ICE circuitry or a special ICE version of a production device (i.e.,
device-ICE).
MPLAB ICD 2: The box that contains the debug control circuitry for the ICD device on
the header or target board. An ICD device can be a production device with built-in ICD
circuitry or a special ICD version of a production device (i.e., device-ICD).
MPLAB ICE 2000/4000: The external emulator box that contains emulation memory,
trace memory, event and cycle timers, and trace/breakpoint logic.
Power-on-Reset Emulation
A software randomization process that writes random values in data RAM areas to
simulate uninitialized values in RAM upon initial power application.
