The ATmega323 AVR Enhanced RISC microcontroller supports powerful and efficient

addressing modes for access to the Program memory (Flash) and Data memory

(SRAM, Register File, and I/O Memory). This section describes the different addressing

modes supported by the AVR architecture. In the figures, OP means the operation code

part of the instruction word. To simplify, not all figures show the exact location of the

addressing bits.
