2467V–AVR–02/11
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
