i is still defined in the resulting object file in the normal way.
far
The far attribute tells the compiler that the variable will not necessarily be allocated in
near (first 8 KB) data space, (i.e., the variable can be located anywhere in data
memory).
mode (
This attribute specifies the data type for the declaration as whichever type corresponds
to the mode mode. This in effect lets you request an integer or floating point type
according to its width. Valid values for mode are as follows:
This attribute is useful for writing code that is portable across all supported MPLAB C30
targets. For example, the following function adds two 32-bit signed integers and returns
a 32-bit signed integer result:
typedef int
int32
add32(int32 a, int32 b)
You may also specify a mode of byte or __byte__ to indicate the mode correspond-
ing to a one-byte integer, word or __word__ for the mode of a one-word integer, and
pointer or __pointer__ for the mode used to represent pointers.
near
The near attribute tells the compiler that the variable is allocated in near data space
(the first 8 KB of data memory). Such variables can sometimes be accessed more
efficiently than variables not allocated (or not known to be allocated) in near data
space.
int num
noload
The noload attribute indicates that space should be allocated for the variable, but that
initial values should not be loaded. This attribute could be useful if an application is
designed to load a variable into memory at runtime, such as from a serial EEPROM.
