PC
Personal Computer or Program Counter.
PC Host
Any PC running a supported Windows operating system.
Persistent Data
Data that is never cleared or initialized. Its intended use is so that an application can preserve data across a device
Reset.
Phantom Byte
An unimplemented byte in the dsPIC architecture that is used when treating the 24-bit instruction word as if it were a
32-bit instruction word. Phantom bytes appear in dsPIC hex files.
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/MPLAB X 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.
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 program devices rapidly. It has the
capability to program at various voltage levels and completely 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.
