Introduction

The

JEDEC

(Joint

Electron

Device

Engineering

Council)

format

is

used

to

transfer

fuse

and

test

vector

data

between

the

programmer

and

a

host

computer.

Code

91

is

full

format

and

includes

all

the

data

fields

(such

as

note

and

test

fields)

described

on

the

following

pages.

Code

92

is

the

Kernel,

or

shorter,

format.

The

JEDEC

Kernel

format

includes

only

the

minimum

information

needed

for

the

programming;

it

does

not,

for

example,

include

information

fields

or

test

vector

fields.

Prior

to

transferring

a

JEDEC

file,

the

appropriate

Logic

device

must

be

selected.

JEDEC's

legal

character

set

consists

of

all

the

printable

ASCII

characters

and

four

control

characters.

The

four

allowable

control

characters

are

STX,

ETX,

CR

(RETURN),

and

LF

(line

feed).

Other

control

characters,

such

as

ESC

or

BREAK,

should

not

be

used.

Note:

This

is

Data

Corporation

's

implementation

of

JEDEC

Standard

3A.

BNF

Rules

and

Standard

Definitions

The

Backus-Naur

Form

(BNF)

is

used

in

the

description

here

to

define

the

syntax

of

the

JEDEC

format.

BNF

is

a

shorthand

notation

that

follows

these

rules:

::

=

denotes

"is

defined

as.”

Characters

enclosed

by

single

quotes

are

literals

(required).

Angle

brackets

enclose

identifiers.

Square

brackets

enclose

optional

items.

Braces

{}

enclose

a

repeated

item.

The

item

may

appear

zero

or

more

times.

Vertical

bars

indicate

a

choice

between

items.

Repeat

counts

are

given

by

a

:

n

suffix.

For

example,

a

6-digit

number

would

be

defined

as:

<number>

::

=

<digit>:6

For

example,

in

words

the

definition

of

a

person's

name

reads:

The

full

name

consists

of

an

optional

title

followed

by

a

first

name,

a

middle

name,

and

a

last

name.

The

person

may

not

have

a

middle

name,

or

may

have

several

middle

names.

The

titles

consist

of:

Mr.,

Mrs.,

Ms.,

Miss,

and

Dr.

The

BNF

definition

for

a

person's

name

is:

<full

name>

::

=

[<title>]

<f.

name>

{<m.name>}

<1.

name>

<title>

::

=

，Mr.'

「

Mrs.'

「

Miss'
