The I/O space definition of the ATtiny11/12 is shown in the following table:
Table 5. ATtiny11/12 I/O Space
Note:
All the different ATtiny11/12 I/O and peripherals are placed in the I/O space. The differ-
ent I/O locations are accessed by the IN and OUT instructions transferring data between
the 32 general-purpose working registers and the I/O space. I/O registers within the
address range $00 - $1F are directly bit-accessible using the SBI and CBI instructions.
In these registers, the value of single bits can be checked by using the SBIS and SBIC
instructions. Refer to the Instruction Set Summary for more details.
For compatibility with future devices, reserved bits should be written to zero if accessed.
Reserved I/O memory addressed should never be written.
The different I/O and peripherals control registers are explained in the following
sections.
The ATtiny11/12 AVR RISC Microcontroller supports powerful and efficient addressing
modes. This section describes the different addressing modes supported in the
ATtiny11/12. In the figures, OP means the operation code part of the instruction word.
To simplify, not all figures show the exact location of the addressing bits.
