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:

<title> :: = ‘Mr.’ | ‘Mrs.’ | ‘Ms.’ | ‘Miss’ | ‘Dr.’

The following standard definitions are used throughout the rest of this

document:

<digit> :: = ‘0’ | ‘1’ | ‘2’ | ‘3’ | ‘4’ | ‘5’ | ‘6’ | ‘7’ | ‘8’ | ‘9’

<hex-digit> :: = <digit> | ‘A’ | ‘B’ | ‘C’ | ‘D’ | ‘E’ | ‘F’

<binary-digit> :: = ‘0’ | ‘1’

<number> :: = <digit> {<digit>}

<delimiter> :: = <del> {<del>}

<space> :: = <ASCII 20 hex> | “

<valid character> :: = <printable character> | <carriage return> |

<field character> :: = <ASCII 20 hex... 29 hex> | <ASCII 2B hex... 7E

hex> | <carriage return> | <line feed>

The Design Specification

Field

<design spec> ::= {<field character>}’*’

The first field sent in a JEDEC transmission is the design specification.

Both the full and kernel JEDEC formats accept the design specification

field. This field is mandatory and does not have an identifier (such as an

asterisk) signaling its beginning. The design specification field consists of

general device information. It could, for example, consist of the following

information: your name, your company’s name, the date, the device

name and manufacturer, design revision level, etc. This field is

terminated by an asterisk character. Examine the sample transmission

shown on the next page of this description—the first three lines of the file

comprise the design specification field. The programmer ignores the

contents of this field for downloads and places “Data I/O” in this field for

upload operations.

Note: You do not need to send any information in this field if you do not wish to;

a blank field, consisting of the terminating asterisk, is a valid design

specification field.

The Transmission

Checksum Field

<xmit checksum> ::= <hex digit>:4

The transmission checksum is the last value sent in a JEDEC

transmission. The full JEDEC format requires the transmission checksum.

The checksum is a 16-bit value, sent as a 4-digit hex number, and is the

sum of all the ASCII characters transmitted between (and including) the

STX and ETX. The parity bit is excluded in the calculation of the

transmission checksum.

Some computer systems do not allow you to control what characters are

sent, especially at the end of a line. You should set up the equipment so

that it will accept a dummy value of 0000 as a valid checksum. This zero

checksum is a way of disabling the transmission checksum while still

keeping within the JEDEC format rules.

JEDEC Full Format, Code 91

The full JEDEC format consists of a start-of-text character (STX), various

fields, an end-of-text character (ETX), and a transmission checksum. A

sample JEDEC transmission sent in the full format is shown in

Figure D-18. Each of the fields is described on the following pages.
