ICCV8 for AVR – C Compiler for Atmel AVRAssembly InstructionsThis chapter lists all the supported AVR instructions. Most of them use the samesyntax as the Atmel assembler. Please refer to Atmel documentation for completeinformation on the instruction set. Newer AVRs implement some new instructions thatare not available in the original AVR design. Roughly speaking, there are threegenerations of AVR instructions: Classic AVRs (e.g., 8515), original MegaAVRs (e.g.,Mega103), and the newest Enhanced MegaAVRs (e.g., Mega48). Some instructions,such as CALL and JMP, are only available for devices with larger than 8K bytes ofcode memory.
