Non-Volatile Storage
A storage device whose contents are preserved when its power is off.
NOP
No Operation. An instruction that has no effect when executed except to advance the
program counter.
Object Code
The machine code generated by an assembler or compiler.
Object File
A file containing machine code and possibly debug information. It may be immediately
executable or it may be relocatable, requiring linking with other object files, e.g.
libraries, to produce a complete executable program.
Object File Directives
Directives that are used only when creating an object file.
Off-Chip Memory
Off-chip memory refers to the memory selection option for the PIC17CXXX or
PIC18CXXX device where memory may reside on the target board, or where all
program memory may be supplied by the Emulator. The Memory tab accessed from
Options > Development Mode provides the Off-Chip Memory selection dialog box.
Opcodes
Operational Codes. See Mnemonics.
Operators
Symbols, like the plus sign ‘+’ and the minus sign ‘-’, that are used when forming
well-defined expressions. Each operator has an assigned precedence that is used to
determine order of evaluation.
OTP
One Time Programmable. EPROM devices that are not in windowed packages. Since
EPROM needs ultraviolet light to erase its memory, only windowed devices are
erasable.
Pass Counter
A counter that decrements each time an event (such as the execution of an instruction
at a particular address) occurs. When the pass count value reaches zero, the event is
satisfied. You can assign the Pass Counter to break and trace logic, and to any
sequential event in the complex trigger dialog.
PC
Personal Computer or Program Counter.
PC Host
Any IBM
system.
PICmicro MCUs
PICmicro microcontrollers (MCUs) refers to all Microchip microcontroller families.
PICSTART Plus
A developmental device programmer from Microchip. Programs 8-, 14-, 28- and 40-pin
PICmicro microcontrollers. Must be used with MPLAB IDE Software.
Pod, Emulator
The external emulator box that contains emulation memory, trace memory, event and
cycle timers and trace/breakpoint logic.
