    Instruction Execution Timing
    This section describes the general access timing concepts for instruction execution. The Atmel
    AVR CPU is driven by the CPU clock, CLK
    CPU, directly generated from the selected clock
    source for the chip. No internal clock division is used.
    Figure 3-5 shows the parallel instruction fetches and instruction executions enabled by the Har-
    vard architecture and the fast-access Register File concept. This is the basic pipelining concept
    to obtain up to 1MIPS per MHz with the corresponding unique results for functions per cost,
    functions per clocks, and functions per power-unit.
    Figure 3-5.
    The Parallel Instruction Fetches and Instruction Executions
    Figure 3-6 shows the internal timing concept for the Register File. In a single clock cycle an ALU
    operation using two register operands is executed, and the result is stored back to the destina-
    tion register.
    Figure 3-6.
