The X-, Y- and Z- Registers
Figure 3-4.
Most of the instructions operating on the Register File have direct access to all registers, and
most of them are single cycle instructions.
The Register File is located in a separate address space, so the registers are not accessible as
data memory.
The registers R26..R31 have added functions besides their general-purpose usage.
These registers can form 16-bit address pointers for addressing of the Data Memory. The three
address registers is called the X-, Y-, and Z-register. The Z-register can also be used as an
address pointer to read from and/or write to the Flash Program Memory, Signature Rows, Fuses
and Lock Bits.
Figure 3-5.
The lowest register address holds the least significant byte (LSB). In the different addressing
modes these address registers have functions as fixed displacement, automatic increment, and
automatic decrement (see the instruction set reference for details).
