Atmel ATtiny24/44/84 [Preliminary]
Data Memory Access Times
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 128/256/512 bytes of internal
data SRAM in the Atmel
modes. The Register File is described in
Figure 6-2.
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
