GlossaryData MemoryOn Microchip MCU and DSC devices, data memory (RAM) is comprised of GeneralPurpose Registers (GPRs) and Special Function Registers (SFRs). Some devices alsohave EEPROM data memory.Debugging <strong>In</strong>formationCompiler and assembler options that, when selected, provide varying degrees of informationused to debug application code. See compiler or assembler documentation fordetails on selecting debug options.Device ProgrammerA tool used to program electrically programmable semiconductor devices such asmicrocontrollers.Digital Signal ControllerA microcontroller device with digital signal processing capability, i.e., Microchip dsP<strong>ICD</strong>SC devices.DirectivesStatements in source code that provide control of the language tool’s operation.DownloadDownload is the process of sending data from a host to another device, such as andebugger, programmer or target board.DSCSee Digital Signal Controller.EEPROMElectrically Erasable Programmable Read Only Memory. A special type of PROM thatcan be erased electrically. Data is written or erased one byte at a time. EEPROMretains its contents even when power is turned off.EmulationThe process of executing software loaded into emulation memory as if it were firmwareresiding on a microcontroller device.Emulation MemoryProgram memory contained within the debugger.<strong>Debugger</strong>Hardware that performs emulation.<strong>Debugger</strong> SystemThe <strong>MPLAB</strong> ICE 2000 and <strong>MPLAB</strong> ICE 4000 debugger systems include the pod, processormodule, device adapter, target board, cables, and <strong>MPLAB</strong> IDE software. The<strong>MPLAB</strong> <strong>ICD</strong> 3 system consists of a pod, a driver (and potentially a receiver) card, targetboard, cables, and <strong>MPLAB</strong> IDE software.Environment – IDEThe particular layout of the desktop for application development.Environment – <strong>MPLAB</strong> PM3A folder containing files on how to program a device. This folder can be transferred toa SD/MMC card.EPROMErasable Programmable Read Only Memory. A programmable read-only memory thatcan be erased usually by exposure to ultraviolet radiation.© 2008 Microchip Technology <strong>In</strong>c. DS51766A-page 87
