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.
Precedence
The concept that some elements of an expression are evaluated before
others; (i.e., * and / and -). In MPASM, operators of the same
precedence are evaluated from left to right. Use parentheses to alter the order
of evaluation.
Program Counter
A register that specifies the current execution address.
Program Memory
The memory area in a PICmicro microcontroller where instructions are stored.
Memory in the emulator or simulator containing the downloaded target
application firmware.
Programmer
A device used to program electrically programmable semiconductor devices
such as microcontrollers.
Project
A set of source files and instructions to build the object and executable code
for an application.
PRO MATE
A device programmer from Microchip. Programs all PICmicro microcontrollers
and most memory and K

devices. Can be used with MPLAB IDE or
stand-alone.
Prototype System
A term referring to a user’s target application, or target board.
PWM Signals
Pulse Width Modulation Signals. Certain PICmicro 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 and for
entering data in the Window > Modify command.
RAM
Random Access Memory (Data Memory).
Raw Data
The binary representation of code or data associated with a section.
