ATmega164P/324P/644P
Data Memory Access Times
The 32 general purpose working registers, 64 I/O registers, 160 Extended I/O Registers and the
1024/2048/4096 bytes of internal data SRAM in the ATmega164P/324P/644P are all accessible
through all these addressing modes. The Register File is described in
ter File” on page
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
