ICE 4000 User’s Guide
File Registers
On-chip data memory, including general purpose registers (GPRs) and special function
registers (SFRs).
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 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.
GPR
General Purpose Register. The portion of device data memory (RAM) available for
general use.
Halt
A stop of program execution. Executing Halt is the same as stopping at a breakpoint.
HEX Code
Executable instructions stored in a hexadecimal format 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.
High Level Language
A language for writing programs that is further removed from the processor than
assembly.
ICD
In-Circuit Debugger. MPLAB ICD and MPLAB ICD 2 are Microchip’s in-circuit
debuggers for PIC16F87X and PIC18FXXX devices, respectively. These ICDs work
with MPLAB IDE.
ICE
In-Circuit Emulator. MPLAB ICE 2000 and 4000 are Microchip’s in-circuit emulators
that work with MPLAB IDE.
IDE
Integrated Development Environment. MPLAB IDE is Microchip’s integrated
development environment.
Import
Bring data into the MPLAB IDE from an outside source, such as from a hex file.
Instruction Set
The collection of machine language instructions that a particular processor
understands.
Instructions
A sequence of bits that tells a central processing unit to perform a particular operation
and can contain data to be used in the operation.
Internal Linkage
A function or variable has internal linkage if it can not be accessed from outside the
module in which it is defined.
