Program Memory

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.

ALU30, C30 – 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, pre-

serving registers and performing any other machine-specific requirement specified in

the runtime 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.

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.

In the simulator, real time simply means execution of the microcontroller instructions as

fast as they can be simulated by the host CPU.

Real-Time Watch

A Watch window where the variables change in real-time as the application is run. See

individual tool documentation to determine how to set up a real-time watch. Not all tools

support real-time watches.

Recursive Calls

A function that calls itself, either directly or indirectly.
