ATtiny43U
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 256 bytes of internal data
SRAM in ATtiny43U are all accessible through all these addressing modes. The Register File is
Figure 5-2.

Data Memory Access Times
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
CPU cycles as described in Figure 5-3 on page
Figure 5-3.

EEPROM Data Memory
The ATtiny43U contains 64 bytes of data EEPROM memory. It is organized as a separate data
space, in which single bytes can be read and written. The EEPROM has an endurance of at
least 100,000 write/erase cycles. The access between the EEPROM and the CPU is described
in the following, specifying the EEPROM Address Registers, the EEPROM Data Register, and
the EEPROM Control Register. For a detailed description of Serial data downloading to the
