The I/O space definition of the AT90S2323/2343 is shown in Table 2.
Table 2. AT90S2323/2343 I/O Space
Note:
All AT90S2323/2343 I/Os and peripherals are placed in the I/O space. The 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 section for more details. When using the I/O-specific commands IN
