Data Memory Access Times
2513C–AVR–09/02
When using register indirect addressing modes with automatic pre-decrement and post-
increment, the address registers X, Y, and Z are decremented or incremented.
The 32 general purpose working registers, 64 (+160) I/O Registers, and the 1024 bytes
of internal data SRAM in the ATmega162 are all accessible through all these addressing
modes. The Register File is described in “General Purpose Register File” on page 10.
Figure 9. Data Memory Map
This section describes the general access timing concepts for internal memory access.
The internal data SRAM access is performed in two clk
10.
