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 4000 emulator systems include the pod, processor module,
device adapter, cables and MPLAB IDE software.
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 MPLAB IDE in a standardized format.
Extended Microcontroller Mode
In Extended Microcontroller mode, on-chip program memory as well as external
memory is available. Execution automatically switches to external if the program
memory address is greater than the internal memory space of the PIC17CXXX or
PIC18CXXX 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.
External Symbol
A symbol for an identifier which has external linkage. This may be a reference or a
definition.
External Symbol Resolution
A process performed by the linker in which external symbol definitions from all input
modules are collected in an attempt to resolve all external symbol references. Any
external symbol references which do not have a corresponding definition cause a linker
error to be reported.
External Input Line
An external input signal logic probe line (TRIGIN) for setting an event based upon
external signals.
External RAM
Off-chip Read/Write memory.
Electrically Erasable Programmable Read-Only Memory. A special type of PROM that

retains its contents even when power is turned off.
