It
is
legitimate
for
user
-
specific
startup
code
to
set
up
@
code
{
EIND
}
early
,
for
example
by
means
of
initialization
code
located
in
section
@
code
{.
init3
}.
Such
code
runs
prior
to
general
startup
code
that
initializes
RAM
and
calls
constructors
,
but
after
the
bit
of
startup
code
from
AVR
-
Lib
c
that
sets
@
code
{
EIND
}
to
the
segment
of
startup
code
from
AVR
-
Lib
C
that
sets
@
code
{
EIND
}
to
the
segment
where
the
vector
table
is
located
.
