S19

S-record The format file is Freescale CodeWarrior The compiler generated suffix is .S19 Program file , It is a paragraph written directly into MCU Of ASCII code , English full name ask Motorola format for EEPROM programming.

1、 Format definition and meaning
S-record The maximum of each line is 78 Bytes ,156 Characters
S-record format
type count address data checksum
type( type )：2 Characters . Used to describe the type of record (S0,S1,S2,S3,S5,S7,S8,S9).

count( Count )：2 Characters . Used to form and describe a 16 The value of base , Shows the count of the remaining paired characters in the record .

address( Address )：4 or 6 or 8 Bytes . Used to form and describe a 16 The value of base , It shows the address where the data should be loaded , The length of this part depends on the number of bytes of the load address .2 The address of bytes takes up 4 Characters ,3 The address of bytes takes up 6 Characters ,4 The address of bytes takes up 8 Characters .

data( data )：0—64 character . It is used to compose and describe a that represents the memory loaded data or description information 16 The value of base .

checksum( The checksum )：2 Characters . These characters should be paired and converted into 16 Hexadecimal data when forming a least significant character section , This character section is used to express as supplementary data , The address and database character pairs represent （ Bytes of ） Complement byte The sum of the . That is, the count value 、 Several characters of address field and data field are paired with two characters , Add them together and sum them up , The overflow portion of and is not counted , Only the minimum two characters are reserved NN,checksum =0xFF-0xNN.

S0 Record： The type of record is “S0” (0x5330). The address field is not used , Set with zero (0x0000). The information in the data field is divided into the following four sub domains ：
name( name )：20 Characters , Used to encode unit names
ver( edition )：2 Characters , Used to encode the version number
rev( Revision )：2 Characters , Used to code the revision number
description( describe )：0-36 Characters , Used to encode text notes
This line indicates the beginning of the program , No need to burn memory.

S1 Record： The type of record is “S1” (0x5331). The address field consists of 2 Byte address to illustrate . Data fields consist of loadable data .

S2 Record： The type of record is “S2” (0x5332). The address field consists of 3 Byte address to illustrate . Data fields consist of loadable data .

S3 Record： The type of record is “S3” (0x5333). The address field consists of 4 Byte address to illustrate . Data fields consist of loadable data .

S5 Record： The type of record is “S5” (0x5335). The address field consists of 2 Byte value description , Contains the previously transmitted S1、S2、S3 Recorded count .
No data fields .

S7 Record： The type of record is “S7” (0x5337). The address field consists of 4 Address description of bytes , Contains the start address . No data fields . This line indicates the end of the program , No need to burn memory.

S8 Record： The type of record is “S8” (0x5338). The address field consists of 3 Address description of bytes , Contains the start address . No data fields . This line indicates the end of the program , No need to burn memory.

S9 Record： The type of record is “S9” (0x5339). The address field consists of 2 Address description of bytes , Contains the start address . No data fields . This line indicates the end of the program , No need to burn memory.

According to different description information , Choose one of the three different ending lines above to use

2、EXAMPLE

2.1 example I

S19 First line of document ： S021000036384B50524F47202020313143524541544544204259204541535936384B6D

The first line of translation information ： S0 0000 6 8 K P R O G 1 1 C R E A T E D B Y E A S Y 6 8 K

Color block legend ：module name version number revision number checksum

checksum The algorithm of ：

0x21+0x00+0x00+0x36+0x38+0x4B+0x50+0x52+0x4F+0x47+0x20+0x20+0x20+0x31+0x31+0x43+0x52+0x45+0x41+0x54+0x45+0x44+0x20+0x42+0x59+0x20+0x45+0x41+0x53+0x59+0x36+0x38+0x4B=0x792

checksum=0xFF-0x92=6D

Be careful ：EASy68K Always use S8 record As a closing line .
