Glossary
Accumulator: Register used for storing one of the operands (data) before arithmetic operations such as addition; available with the PIC18F.
Address: A unique identification number (or locator ) for source or destination of data. An address specifies the register or memory location of an operand involved in the instruction.
Address Register: A register used to store the address (memory location) of data.
Address Space: The number of storage location in a microcontrollers's memory that can be directly addressed by the CPU. The addressing range is determined by the number of address bits provided with the CPU.
American Standard Code for Information Interchange (ASCII): An 8-bit code commonly used with microcontrollers for representing alphanumeric codes.
Analog-to-Digital (A/D) Converter: Transforms an analog voltage into its digital equivalent.
AND gate: The output is 1, if all inputs are 1; otherwise the output is 0.
Arithmetic and Logic Unit (ALU): A digital circuit which performs arithmetic and logic operations on two n-bit numbers.
ASIC: Application Specific IC. Chips designed for a specific, limited application. Normally reduces the total manufacturing cost of a product by reducing chip count.
Assembler: A program that translates an assembly language program into a machine language program.
Assembly Language: A type of microcontroller programming language that uses a semi-English-language statement.
Asynchronous Operation: The execution of a sequence ...
