Data Memory Access Times
The 32 general purpose working registers, 64 I/O Registers, and the 256 bytes of internal data
SRAM in the ATtiny44V are all accessible through all these addressing modes. The Register
File is described in
Figure 4-8.
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
