The XMEGA A4 uses the 8/16-bit AVR CPU. The main function of the CPU is program execu-
tion. The CPU must therefore be able to access memories, perform calculations and control
peripherals. Interrupt handling is described in a separate section.
the CPU block diagram.
Figure 6-1.
The AVR uses a Harvard architecture - with separate memories and buses for program and
data. Instructions in the program memory are executed with a single level pipeline. While one
instruction is being executed, the next instruction is pre-fetched from the program memory. This
