2467X–AVR–06/11
ATmega128
The Indirect with Displacement mode reaches 63 address locations from the base address given
by the Y- or Z-register.
When using register indirect addressing modes with automatic pre-decrement and post-incre-
ment, the address registers X, Y, and Z are decremented or incremented.
The 32 general purpose working registers, 64 I/O registers, and the 4096bytes of internal data
SRAM in the ATmega128 are all accessible through all these addressing modes. The Register
file is described in “General Purpose Register File” on page 11.
