Instruction Execution Timing
The AVR Stack Pointer is implemented as two 8-bit registers in the I/O space. The number of
bits actually used is implementation dependent. Note that the data space in some implementa-
tions of the AVR
Register will not be present.
This section describes the general access timing concepts for instruction execution. The AVR
CPU is driven by the CPU clock clk
the chip. No internal clock division is used.

Harvard 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.
