一般我们看到的m0，SHX文件格式都是摩托罗拉文件格式，TI编译系统最后生成的m0文件也就是摩托罗拉文件格式。

The Motorola S-record format is an ASCII encoding for binary data. It is also known as the SREC or S19 format.
An SREC format file consists of a series of ASCII records. All hexadecimal (hex) numbers are Big Endian.
The records have the following structure:
1. Start code, one character, an S.
2. Record type, one digit, 0 to 9, defining the type of the data field.
3. Byte count, two hex digits, indicating the number of bytes (hex digit pairs) that follow in the rest of the record (in the address, data and checksum fields).
4. Address, four, six, or eight hex digits as determined by the record type for the memory location of the first data byte.
5. Data, a sequence of 2n hex digits, for n bytes of the data.
6. Checksum, two hex digits - the one’s complement of the least significant byte sum of the values represented by the two hex digit pairs for the byte count, address and data fields.
There are eight record types, listed below:
| Record | Description | Address Bytes | Data Sequence |
|---|---|---|---|
| S0 | Block header | 2 | Yes |
| S1 | Data sequence | 2 | Yes |
| S2 | Data sequence | 3 | Yes |
| S3 | Data sequence | 4 | Yes |
| S5 | Record count | 2 | No |
| S7 | End of block | 4 | No |
| S8 | End of block | 3 | No |
| S9 | End of block | 2 | No |
The S0 record data sequence contains vendor specific data rather than program data. The record count in the S5 record is stored in the 2-byte address field. The address field of the S7, S8, or S9 records may contain a starting address for the program.
