Download
Download is the process of sending data from a host to another device, such as an
emulator, 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 emulator.
Emulator
Hardware that performs emulation.
Emulator System
The MPLAB ICE 2000 and MPLAB ICE 4000 emulator systems include the pod,
processor module, device adapter, 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.
Event
A description of a bus cycle which may include address, data, pass count, external
input, cycle type (fetch, R/W) and time stamp. Events are used to describe triggers,
breakpoints and interrupts.
Export
Send data out of the MPLAB IDE in a standardized format.
Extended Microcontroller Mode
In extended microcontroller mode, on-chip program memory as well as external mem-
ory is available. Execution automatically switches to external if the program memory
address is greater than the internal memory space of the PIC17 or PIC18 device.
External Label
A label that has external linkage.
External Linkage
A function or variable has external linkage if it can be referenced from outside the
module in which it is defined.
