Epilogue
A portion of compiler-generated code that is responsible for deallocating stack space, restoring registers and
performing any other machine-specific requirement specified in the runtime model. This code executes after any user
code for a given function, immediately prior to the function return.
EPROM
Erasable Programmable Read Only Memory. A programmable read-only memory that can be erased usually by
exposure to ultraviolet radiation.
Error/Error File
An error reports a problem that makes it impossible to continue processing your program. When possible, an error
identifies the source file name and line number where the problem is apparent. An error file contains error messages
and diagnostics generated by a language tool.
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.
Executable Code
Software that is ready to be loaded for execution.
Export
Send data out of the MPLAB IDE/MPLAB X IDE in a standardized format.
Expressions
Combinations of constants and/or symbols separated by arithmetic or logical operators.
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
PIC18 device.
Extended Mode (PIC18 MCUs)
In Extended mode, the compiler will utilize the extended instructions (i.e.,
ADDFSR
,
ADDULNK
,
CALLW
,
MOVSF
,
MOVSS
,
PUSHL
,
SUBFSR
, and
SUBULNK
) and the indexed with literal offset addressing.
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.
