General Purpose Register File
The X-register, Y-register, and Z-register
The Register File is optimized for the Atmel
achieve the required performance and flexibility, the following input/output schemes are sup-
ported by the Register File:
• One 8-bit output operand and one 8-bit result input
• Two 8-bit output operands and one 8-bit result input
• Two 8-bit output operands and one 16-bit result input
• One 16-bit output operand and one 16-bit result input

Most of the instructions operating on the Register File have direct access to all registers, and
most of them are single cycle instructions.
As shown in
directly into the first 32 locations of the user Data Space. Although not being physically imple-
mented as SRAM locations, this memory organization provides great flexibility in access of the
registers, as the X-, Y- and Z-pointer registers can be set to index any register in the file.
The 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 indi-
rect address registers X, Y, and Z are defined as described in
