What is AVR assembler?
The AVR Assembler is the assembler formerly known as AVR Assembler 2 (AVRASM2). For documentation on the instruction set of the AVR family of microcontrollers, refer to the 8-bit AVR Instruction Set Manual.
What is the concept of X Y Z register in AVR?
XYZ is a pointer register, either X or Y or Z. YZ is a pointer register, either Y or Z. s is a bit number in the status register (0 = C, 1 = Z, etc., see the list above) b is a bit number in a general-purpose or I/O register (0 = least significant, 7 = most significant)
Why do we need assembler?
An assembler is a program that converts assembly language into machine code. It takes the basic commands and operations from assembly code and converts them into binary code that can be recognized by a specific type of processor.
Which is the instruction set for the AVR assembler?
The instruction set of the AVR family of microcontrollers is only briefly described, refer to the AVR Data Book (also available on CD-ROM) in order to get more detailed knowl-edge of the instruction set for the different microcontrollers. To get quickly started, the Quick-Start Tutorial is an easy way to get familiar with the Atmel AVR Assembler.

Is the GNU C compiler for Atmel AVR RISC processors?
The GNU C compiler for Atmel AVR RISC processors offers, to embed assembly language code intoC programs. This cool feature may be used for manually optimizing time critical parts of the softwareor to use specific processor instruction, which are not available in the C language.
When do you need to understand assembly language?
●if time-critical in line routines require assembly language portions, it is necessary to understand assembly language, e. g. to understand what the higher-level language compiler produced. Without understanding assembly language you do not have a chance to proceed further in these cases. Short and easy
