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/MPLAB X IDE:
The memory area in a device where instructions are stored. Also, the memory in the
emulator or simulator containing the downloaded target application firmware.
16-bit assembler/compiler:
The memory area in a device where instructions are stored.
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.
Prologue
A portion of compiler-generated code that is responsible for allocating stack space, preserving registers and
performing any other machine-specific requirement specified in the run-time model. This code executes before any
user code for a given function.
Prototype System
A term referring to a user's target application, or target board.
Psect
The OCG equivalent of a GCC section, short for program section. A block of code or data which is treated as a whole
by the linker.
PWM Signals
Pulse Width Modulation Signals. Certain PIC MCU devices have a PWM peripheral.
Qualifier
An address or an address range used by the Pass Counter or as an event before another operation in a complex
trigger.
Radix
The number base, hex, or decimal, used in specifying an address.
RAM
Random Access Memory (Data Memory). Memory in which information can be accessed in any order.
Raw Data
The binary representation of code or data associated with a section.
Read Only Memory
Memory hardware that allows fast access to permanently stored data but prevents addition to or modification of the
data.
Real Time
When an in-circuit emulator or debugger is released from the halt state, the processor runs in Real Time mode and
behaves exactly as the normal chip would behave. In Real Time mode, the real time trace buffer of an emulator is
enabled and constantly captures all selected cycles, and all break logic is enabled. In an in-circuit emulator or
debugger, the processor executes in real time until a valid breakpoint causes a halt, or until the user halts the
execution.
