The
C
field,
the
fuse
information
checksum
field,
is
used
to
detect
transmitting
and
receiving
errors.
The
field
contains
a
16-bit
sum
(modulus
65535)
computed
by
adding
8-bit
words
containing
the
fuse
states
for
the
entire
device.
The
8-bit
words
are
formed
as
shown
in
the
following
figure.
Unused
bits
in
the
final
8-bit
word
are
set
to
zero
before
the
checksum
is
calculated.

Following
is
an
example
of
full
specification
of
the
L,
C,
and
F
fields:
Following
is
an
alternate
way
of
defining
the
same
fuse
states
using
the
K
field:
Another

where
F

are
not
specified:
The
Security
Fuse
Field
(G)
〈
security
fuse

'
G
'

binary-digit
>
'
*
'
The
JEDEC
G
field
is
used
to
enable
the
security
fuse
of
some
logic
devices.
To
enable
the
fuse,
send
a
1
in
the
G
field:
*
The
Note
Field
(N)
<note>::=,N,<field
characters〉'*'
The
note
field
is
used
in
JEDEC
transmission
to
insert
notes
or
comments.
The
programmer
will
ignore
this
field;
it
will
not
be
interpreted
as
data.
An
example
of
a
note
field
would
be:
N

The
Value
Fields
(QF,
QP,
and
QV)
JEDEC
value
fields
define
values
or
limits
for
the
data
file,
such
as
number
of
fuses.
The
QF
subfield
defines
the
number
of
fuses
in
the
device.
All
of
the
value
fields
must
occur
before
any
device
programming
or
testing
fields
appear
in
the
data
file.
Files
with
ONLY
testing
fields
do
not
require
the
QF
field,
and
fields
with
ONLY
programming
data
do
not
require
the
QP
and
QV
fields.
The
QF
subfield
tells
the
programmer
how
much
memory
to
reserve
for
fuse
data,
the
number
of
fuses
to
set
to
the
default
condition,
and
the
number
of
fuses
to
include
in
the
fuse
checksum.
The
QP
subfield
defines
the
number
of
pins
or
test
conditions
in
the
test
vector,
and
the
QV
subfield
defines
the
maximum
number
of
test
vectors.

The
P
Field
The
P
field
remaps
the
device
pinout
and
is
used
with
the
V
(test
vector)
field.
An
asterisk
terminates
the
field.
The
syntax
of
the
field
is
as
follows:
<pin
Hst>::='P'vpin

<pin

The
following

a

The

JEDEC
U
and
E
Fields
As
of
Version
2.5,
the
programmer
supports
the
optional
JEDEC
U
(user
data)
and
E
(electrical
data)
fields.
The
U
and
E
fields
are
described
below.
Note:
Implementation
of
the
JEDEC
U
and
E
fields
is
not
part
of
the
JEDEC-
3c
(JESD3-C)
standard.
User
Data
(U
Field)
The
U
field
allows
user
data
fuses
that
do
not
affect
the
logical
or
electrical
functionality
of
the
device
to
be
specified
in
JEDEC
files.
For
instance,
the
U
field
can
be
used
to
specify
the
User
Data
Signature
fuse
available
in
some
types
of
PLD
devices
because
this
fuse
contains
information
only
(it
has
no
logical
or
electrical
functionality).
Note:
To
have
the
JEDEC
U
field
processed
correctly,
you
must
select
the
device
before
downloading
the
JEDEC
6/e.
The
following
guidelines
apply
to
the
U
field:
•
The
U
field
must
be
included
for
devices
with
U
fuses.
•
Each
U-field
cell
must
be
explicitly
provided
if
the
U
field
is
present.
•
The
F
(default
fuse
state)
field
does
not
affect
U
fuses.
•
There
can
only
be
one
U
field
in
a
JEDEC
file.
•
The
U
field
fuses
must
be
listed
in
the
order
they
appear
in
the
device.
•
The
U
field
must
be
listed
after
the
L
field
and
E
field
(if
used),
and
before
the
V
(test
vector)
field
(if
used).
•
The
U
field
is
specified
using
binary
numbers,
since
the
full
number
of
U-field
cells
is
otherwise
unknown.
•
The
number
of
cells
specified
in
the
U
field
is
not
included
in
the
QF
(number
of
fuses)
field.

Electrical
Data
(E
field)
•
The
U-field
cells
are
not
included
in
the
C
(fuse
checksum)
field.
•
The
U
field
reads
left
to
right
to
be
consistent
with
the
L
(fuse
list)
and
E
fields.
The
syntax
for
the
U
field
is
as
follows:
The
character
U
begins
the
U
field
and
is
followed
by
one
binary
digit
for
each
U
fuse.
Each
binary
digit
indicates
one
of
two
possible
states
(zero,
specifying
a
low-resistance
link,
or
one,
specifying
a
high-resistance
link)
for
each
fuse.
For
example,
The
E
field
allows
special
feature
fuses
that
do
not
affect
the
logic
function
of
the
device
to
be
specified
in
JEDEC
files.
The
following
guidelines
apply
to
the
E
field:
•
The
E-field
cell
must
be
explicitly
provided
if
the
E
field
is
present.
•
The
F
(default
fuse
state)
field
does
not
affect
E
fuses.
•
There
can
only
be
one
E
field
in
a
JEDEC
file.
•
The
E
field
fuses
must
be
listed
in
the
order
they
appear
in
the
device.
•
The
E
field
must
be
listed
before
the
C
(checksum)
field.
If
the
U
field
is
used,
the
E
field
must
come
before
the
U
(user
data)
field.
•
The
E
field
is
specified
using
binary
numbers,
since
the
full
number
of
E-field
cells
is
otherwise
unknown.
•
The
number
of
cells
specified
in
the
E
field
is
not
included
in
the
QF
(number
of
fuses)
field.
•
The
E-field
cells
are
included
in
the
C
(fuse
checksum)
field.
•
The
E
field
reads
left
to
right
for
the
purpose
of
checksum
calculation.
The
syntax
for
the
E
field
is
as
follows:
The
character
E
begins
the
E
field
and
is
followed
by
one
binary
digit
for
each
E
fuse.
Each
binary
digit
indicates
one
of
two
possible
states
(zero,
specifying
a
low-resistance
link,
or
one,
specifying
a
high-resistance
link)
for
each
fuse.
