Reentrant
A function that may have multiple, simultaneously active instances. This may happen
due to either direct or indirect recursion or through execution during interrupt
processing.
Relaxation
The process of converting an instruction to an identical, but smaller instruction. This is
useful for saving on code size. MPLAB XC16 currently knows how to
relax a CALL
instruction into an
RCALL instruction. This is done when the symbol that is being called
is within +/- 32k instruction words from the current instruction.
Relocatable
An object whose address has not been assigned to a fixed location in memory.
Relocatable Section
16-bit assembler – A section whose address is not fixed (absolute). The linker assigns
addresses to relocatable sections through a process called relocation.
Relocation
A process performed by the linker in which absolute addresses are assigned to
relocatable sections and all symbols in the relocatable sections are updated to their
new addresses.
ROM
Read Only Memory (Program Memory). Memory that cannot be modified.
Run
The command that releases the emulator from halt, allowing it to run the application
code and change or respond to I/O in real time.
Run-time Model
Describes the use of target architecture resources.
Runtime Watch
A Watches window where the variables change in as the application is run. See
individual tool documentation to determine how to set up a runtime watch. Not all tools
support runtime watches.
S
Scenario
For MPLAB SIM simulator, a particular setup for stimulus control.
Section
The GCC equivalent of an OCG psect. A block of code or data which is treated as a
whole by the linker.
Section Attribute
A GCC characteristic ascribed to a section (e.g., an
access section).
Sequenced Breakpoints
Breakpoints that occur in a sequence. Sequence execution of breakpoints is
bottom-up; the last breakpoint in the sequence occurs first.
Serialized Quick Turn Programming
Serialization allows you to program a serial number into each microcontroller device
that the Device Programmer programs. This number can be used as an entry code,
password or ID number.
