Glossary
File Registers
On-chip general purpose and special function registers.
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 PICmicro 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.
GPR
See Data Memory.
Halt
A function that stops the emulator. Executing Halt is the same as stopping at a
break point. The program counter stops and the user can inspect and change
register values and single step through code.
Hex Code
Executable instructions assembled or compiled from source code into
standard hexadecimal format code. Also called executable or machine code.
Hex code is contained in a hex file.
Hex File
An ASCII file containing hexadecimal addresses and values (hex code)
suitable for programming a device. This format is readable by a device
programmer.
High Level Language
A language for writing programs that is of a higher level of abstraction from
the processor than assembler code. High level languages (such as C) employ
a compiler to translate statements into machine instructions that the target
processor can execute.
ICD
In-Circuit Debugger. MPLAB ICD is Microchip’s in-circuit debugger for
PIC16F87X devices. MPLAB ICD works with MPLAB IDE.
ICE
In-Circuit Emulator. MPLAB ICE is Microchip’s in-circuit emulator that works
with MPLAB IDE.
IDE
Integrated Development Environment. An application that has multiple
functions for firmware development. The MPLAB IDE integrates a compiler,
an assembler, a project manager, an editor, a debugger, a simulator and an
