Glossary
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.
PRO MATE II
A device programmer from Microchip. Programs all PICmicro microcontrollers and
most memory and Keeloq devices. Can be used with MPLAB IDE or stand-alone.
Program Counter
The location that contains the address of the instruction that is currently executing.
Program Memory
The memory area in a device where instructions are stored. Also, the memory in the
emulator or simulator containing the downloaded target application firmware.
Project
A set of source files and instructions to build the object and executable code for an
application.
Prototype System
A term referring to a user's target application, or target board.
PWM Signals
Pulse Width Modulation Signals. Certain PICmicro 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.
Real-Time
When released from the halt state in the emulator or MPLAB ICD mode, 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 MPLAB ICE is enabled and constantly
captures all selected cycles, and all break logic is enabled. In the emulator or MPLAB
ICD, the processor executes in real-time until a valid breakpoint causes a halt, or until
the user halts the emulator. In the simulator real-time simply means execution of the
microcontroller instructions as fast as they can be simulated by the host CPU.
Recursion
The concept that a function or macro, having been defined, can call itself. Great care
should be taken when writing recursive macros; it is easy to get caught in an infinite
loop where there will be no exit from the recursion.
ROM
Read Only Memory (Program Memory). Memory that cannot be modified.
Run
The command that releases the emulator from halt, allowing it to run the application
code and change or respond to I/O in real time.
