NOROOT, ROOT
NOROOT means that the segment part is discarded by the linker if no symbols in this segment part are referred to.
Normally, all segment parts except startup code and interrupt vectors should set this flag.
The default mode is ROOT which indicates that the segment part must not be discarded.

REORDER, NOREORDER
REORDER allows the linker to reorder segment parts. For a given segment, all segment parts must specify the same state for this flag.
The default mode is NOREORDER which indicates that the segment parts must remain in order.

SORT, NOSORT
SORT means that the linker sorts the segment parts in decreasing alignment order. For a given segment,
all segment parts must specify the same state for this flag. The default mode is NOSORT
which indicates that the segment parts are not sorted.

Beginning an absolute segment
Use ASEG to set the absolute mode of assembly, which is the default at the beginning of
a module.
If the parameter is omitted, the start address of the first segment is 0, and subsequent
segments continue after the last address of the previous segment.
Note: If a move of an immediate value to an absolute address, for example
mov #0x1234, 0x300
is made in a relocatable or absolute segment, the offset is calculated as if the code begun
at address 0x0000. The assembler does not take into account the placement of the
segment.

Beginning a named absolute segment
Use ASEGN to start a named absolute segment located at the address address.
This directive has the advantage of allowing you to specify the memory type of the
segment.

Beginning a relocatable segment
Use RSEG to start a new segment. The assembler maintains separate location counters
(initially set to zero) for all segments, which makes it possible to switch segments and
mode anytime without having to save the current program location counter.
Up to 65536 unique, relocatable segments can be defined in a single module.

Beginning a common segment
Use COMMON to place data in memory at the same location as COMMON segments from
other modules that have the same name. In other words, all
COMMON segments of the
same name start at the same location in memory and overlay each other.
Obviously, the
COMMON segment type should not be used for overlaid executable code.
A typical application would be when you want several different routines to share a
reusable, common area of memory for data.
It can be practical to have the interrupt vector table in a
COMMON segment, thereby
allowing access from several routines.
The final size of the
COMMON segment is determined by the size of largest occurrence of
this segment. The location in memory is determined by the XLINK
-Z command; see
the IAR Linker and Library Tools Reference Guide.
Use the
align parameter in any of the above directives to align the segment start
address.
