Figure 4-2 below shows the structure of the 16 general purpose working registers in the CPU.
Figure 4-2.
AVR CPU General Purpose Working Registers
Note:
A typical implementation of the AVR register file includes 32 general prupose registers but ATtiny4/5/9/10 implement
only 16 registers. For reasons of compatibility the registers are numbered R16...R31, not R0...R15.
Most of the instructions operating on the Register File have direct access to all registers, and most of them are sin-
gle cycle instructions.
4.4.1
The X-register, Y-register, and Z-register
Registers R26..R31 have some added functions to their general purpose usage. These registers are 16-bit
address pointers for indirect addressing of the data space. The three indirect address registers X, Y, and Z are
defined as described in Figure 4-3.
