The embedded AVR core I/Os and peripherals, and all the virtual FPGA peripherals are placed
in the I/O space. The different I/O locations are directly accessed by the IN and OUT instructions
transferring data between the 32 x 8 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. When using the I/O specific instructions IN, OUT, the I/O register address
$00 – $3F are used, see
added to this address. All I/O register addresses throughout this document are shown with the
SRAM address in parentheses.
