Welcome to the ATMEL AVR Assembler.

The Assembler generates fixed code allocations, consequently no linking is necessary.

The instruction set of the AVR family of microcontrollers is only briefly described, refer to the AVR Data Book in order to get more detailed knowledge of the instruction set for the different microcontrollers.

The AVR Assembler, is the Assembler formerly known as AVR Assembler 2 (AVRASM2). The former AVRASM distributed with AVR Studio 4 has now been obsoleted and will not be distributed with current products.

The content in this document is an adaptation of the original 8-bit AVR Instruction Set.
