Glossary
Data Memory
On Microchip MCU and DSC devices, data memory (RAM) is comprised of General
Purpose Registers (GPRs) and Special Function Registers (SFRs). Some devices also
have EEPROM data memory.
Debugging Information
Compiler and assembler options that, when selected, provide varying degrees of infor-
mation used to debug application code. See compiler or assembler documentation for
details on selecting debug options.
Device Programmer
A tool used to program electrically programmable semiconductor devices such as
microcontrollers.
Digital Signal Controller
A microcontroller device with digital signal processing capability, i.e., Microchip dsPIC
DSC devices.
Directives
Statements in source code that provide control of the language tool's operation.
Download
Download is the process of sending data from a host to another device, such as an
debugger, programmer or target board.
DSC
See Digital Signal Controller.
EEPROM
Electrically Erasable Programmable Read Only Memory. A special type of PROM that
can be erased electrically. Data is written or erased one byte at a time. EEPROM
retains its contents even when power is turned off.
Emulation
The process of executing software loaded into emulation memory as if it were firmware
residing on a microcontroller device.
Emulation Memory
Program memory contained within the debugger.
Debugger
Hardware that performs emulation.
Debugger System
The MPLAB ICE 2000 and MPLAB ICE 4000 debugger systems include the pod, pro-
cessor module, device adapter, target board, cables, and MPLAB IDE software. The
MPLAB ICD 3 system consists of a pod, a driver (and potentially a receiver) card, target
board, cables, and MPLAB IDE software.
Environment – IDE
The particular layout of the desktop for application development.
Environment – MPLAB PM3
A folder containing files on how to program a device. This folder can be transferred to
a SD/MMC card.
EPROM
Erasable Programmable Read Only Memory. A programmable read-only memory that
can be erased usually by exposure to ultraviolet radiation.
