I/O Memory
The I/O space definition of the AT43USB353M is shown in Table 7:
All AT43USB353M I/O and peripherals, except for the USB hardware registers, 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
Table 7.
