Format,

The
Extended
Tektronix
Hexadecimal
format
has
three
types
of
records:
data,
symbol,
and
termination
records.
The
data
record
contains
the
object
code.
Information
about
a
program
section
is
contained
in
the
symbol
record
(the
programmer
ignores
symbol
records),
and
the
termination
record
signifies
the
end
of
a
module.
The
data
record
(see
sample
below)
contains
a
header
field,
a
load
address,
and
the
object
code.

The
load
address
determines
where
the
object
code
will
be
located.
This
is
a
variable
length
number
that
may
contain
up
to
17
characters.
The
first
number
determines
the
address
length,
with
a
zero
signifying
a
length
of
16.
The
remaining
characters
of
the
data
record
contain
the
object
code,
2
characters
per
byte.
When
you
copy
data
to
the
port
or
to
RAM,
set
the
high-order
address
if
the
low-order
is
not
at
the
default
value.

Motorola
32-Bit
Format,
Code
95
The
Motorola
32-bit
format
closely
resembles
the
Motorola
EXORmacs
format,
the
main
difference
being
the
addition
of
the
S3
and
S7
start
characters.
The
S3
character
is
used
to
begin
a
record
containing
a
4
-byte
address.
The
S7
character
is
a
termination
record
for
a
block
of
S3
records.
The
address
field
for
an
S7
record
may
optionally
contain
the
4-byte
instruction
address
that
identifies
where
control
is
to
be
passed
and
is
ignored
by
the
programmer.

shows
a
sample

the
Motorola
32-bit

data
files
may
begin
with
an
optional
sign-on
record,
initiated
by
the
start
characters
SO
or
S5.
Data
records
start
with
an
8-
or
1
O-character
prefix
and
end
with
a
2-character
suffix.
Each
data
record
begins
with
the
start
characters
SI,
S2,
or
S3:
SI
if
the
following
address
field
has
4
characters,
S2
if
it
has
6
characters,
S3
if
it
has
8
characters.
The
third
and
fourth
characters
represent
the
byte
count,
which
expresses
the
number
of
data,
address,
and
checksum
bytes
in
the
record.
The
address
of
the
first
data
byte
in
the
record
is
expressed
by
the
last
4
characters
of
the
prefix
(6
characters
for
addresses
above
hexadecimal
FFFF,
and
8
characters
for
addresses
above
hexadecimal
FFFFFF).
Data
bytes
follow,
each
represented
by
2
hexadecimal
characters.
The
number
of
data
bytes
occurring
must
be
3,
4,
or
5
less
than
the
byte
count.
The
suffix
is
a
2-character
checksum,
the
one's
complement
(in
binary)
of
the
preceding
bytes
in
the
record,
including
the
byte
count,
address,
and
data
bytes.
The
end-of-file
record
begins
with
an
S8
or
S9
start
character.
Following
the
start
characters
are
the
byte
count,
the
address,
and
a
checksum.
The
maximum
record
length
is
250
data
bytes.
