Data Memory
On Microchip MCU and DSC devices, data memory (RAM) is comprised of General
Purpose Registers (GPRs) and Special Function Registers (SFRs). Some devices also
have EEPROM data memory.
Debugging Information
Compiler and assembler options that, when selected, provide varying degrees of infor-
mation used to debug application code. See compiler or assembler documentation for
details on selecting debug options.
Deprecated Features
Features that are still supported for legacy reasons, but will eventually be phased out
and no longer used.
Device Programmer
A tool used to program electrically programmable semiconductor devices such as
microcontrollers.
Digital Signal Controller
A microcontroller device with digital signal processing capability, i.e., Microchip dsPIC
DSC devices.
Digital Signal Processing
The computer manipulation of digital signals, commonly analog signals (sound or
image) which have been converted to digital form (sampled).
Digital Signal Processor
A microprocessor that is designed for use in digital signal processing.
Directives
Statements in source code that provide control of the language tool’s operation.
Download
Download is the process of sending data from a host to another device, such as an
debugger, programmer or target board.
DSC
See Digital Signal Controller.
DSP
See Digital Signal Processor.
DWARF
Debug With Arbitrary Record Format. DWARF is a debug information format for ELF
files.
EEPROM
Electrically Erasable Programmable Read Only Memory. A special type of PROM that
can be erased electrically. Data is written or erased one byte at a time. EEPROM
retains its contents even when power is turned off.
ELF
Executable and Linking Format. An object file of this format contains machine code.
Debugging and other information is specified in with DWARF. ELF/DWARF provide
better debugging of optimized code than COFF.
Emulation
The process of executing software loaded into emulation memory as if it were firmware
residing on a microcontroller device.
