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.
External RAM
Off-chip Read/Write memory.
F
Fatal Error
An error that will halt compilation immediately. No further messages will be produced.
File Registers
On-chip data memory, including General Purpose Registers (GPRs) and Special
Function Registers (SFRs).
Filter
Determine by selection what data is included/excluded in a trace display or data file.
Fixup
The process of replacing object file symbolic references with absolute addresses after
relocation by the linker.
Flash
A type of EEPROM where data is written or erased in blocks instead of bytes.
FNOP
Forced No Operation. A forced NOP cycle is the second cycle of a two-cycle
instruction. Since the PIC microcontroller architecture is pipelined, it prefetches the
next instruction in the physical address space while it is executing the current
instruction. However, if the current instruction changes the program counter, this
prefetched instruction is explicitly ignored, causing a forced NOP cycle.
Frame Pointer
A pointer that references the location on the stack that separates the stack-based
arguments from the stack-based local variables. Provides a convenient base from
which to access local variables and other values for the current function.
