Instruction Execution Timing
SPH and SPL – Stack Pointer High and Stack pointer Low
RAMPZ – Extended Z-pointer Register for ELPM/SPM
Note:
Table 4-2.
For ELPM/SPM instructions, the Z-pointer is a concatenation of RAMPZ, ZH, and ZL, as shown
in Figure 4-4. Note that LPM is not affected by the RAMPZ setting.
Figure 4-4.
The actual number of bits is implementation dependent. Unused bits in an implementation will
always read as zero. For compatibility with future devices, be sure to write these bits to zero.
This section describes the general access timing concepts for instruction execution. The AVR
CPU is driven by the CPU clock clk
chip. No internal clock division is used.
Figure 4-5 on page 15
by the Harvard architecture and the fast-access Register File concept. This is the basic pipelin-
ing concept to obtain up to 1 MIPS per MHz with the corresponding unique results for functions
per cost, functions per clocks, and functions per power-unit.
