@item io
@itemx io (@var{addr})
Variables with the @code{io} attribute are used to address
memory-mapped peripherals in the io address range.
If an address is specified, the variable
is assigned that address, and the value is interpreted as an
address in the data address space.
Example:
@smallexample
volatile int porta __attribute__((io (0x22)));
@end smallexample
The address specified in the address in the data address range.
Otherwise, the variable it is not assigned an address, but the
compiler will still use in/out instructions where applicable,
assuming some other module assigns an address in the io address range.
Example:
@smallexample
extern volatile int porta __attribute__((io));
@end smallexample
@item io_low
@itemx io_low (@var{addr})
This is like the @code{io} attribute, but additionally it informs the
compiler that the object lies in the lower half of the I/O area,
allowing the use of @code{cbi}, @code{sbi}, @code{sbic} and @code{sbis}
instructions.
@item address
@itemx address (@var{addr})
Variables with the @code{address} attribute are used to address
memory-mapped peripherals that may lie outside the io address range.
@smallexample
volatile int porta __attribute__((address (0x600)));
@end smallexample
