PIC MCUs
PIC microcontrollers (MCUs) refers to all Microchip microcontroller families.
PICkit 2 and 3
Microchip’s developmental device programmers with debug capability through Debug
Express. See the Readme files for each tool to see which devices are supported.

Plug-ins
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
The enclosure for an in-circuit emulator or debugger. Other names are “Puck”, if the
enclosure is round, and “Probe”, not be confused with logic probes.

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.

Pragma
A directive that has meaning to a specific compiler. Often a pragma is used to convey
implementation-defined information to the compiler. MPLAB C30 uses attributes to
convey this information.

Precedence
Rules that define the order of evaluation in expressions.
Production Programmer
A production programmer is a programming tool that has resources designed in to pro-
gram devices rapidly. It has the capability to program at various voltage levels and com-
pletely adheres to the programming specification. Programming a device as fast as
possible is of prime importance in a production environment where time is of the
essence as the application circuit moves through the assembly line.

Profile
For MPLAB SIM simulator, a summary listing of executed stimulus by register.
Program Counter
The location that contains the address of the instruction that is currently executing.
Program Counter Unit
16-bit assembler – A conceptual representation of the layout of program memory. The
program counter increments by 2 for each instruction word. In an executable section,
2 program counter units are equivalent to 3 bytes. In a read-only section, 2 program
counter units are equivalent to 2 bytes.

Program Memory
MPLAB IDE – The memory area in a device where instructions are stored. Also, the
memory in the emulator or simulator containing the downloaded target application firm-
ware.

Project
A project contains the files needed to build an application (source code, linker script
files, etc.) along with their associations to various build tools and build options.
