Zt: Commonly Used single-chip microcomputer output format-Motorola S-records (S19 files)

Motorola S-records hexadecimal file format is a common embedded format except intel hex. below is its format:
+ ------------------- // -------------------- // ----------------------- +
| Type (hex1) | count (hex 1) | address | data | checksum (from count to checksum, total 0xFF) |
+ ------------------- // -------------------- // ----------------------- +
S0: Id record. The address field length is 2 bytes and is filled with 0000. The data area records information such as the module name and version.
S1: data record. The address field length is 2 bytes, and the data area is the data content.
S2: data record. The address field is 3 bytes in length and the data area is the data content.
S3: data record. The address field length is 4 bytes, and the data area is the data content.
S5: the number of statistical records (S1, S2, S3) with a length of 2 bytes. The data area is empty.
S7: operation record. The address field is 4 bytes long. The content is the address of the program startup and the data field is empty.
S8: running record. The address field is 3 bytes in length. The content is the address of the program startup and the data field is empty.
S9: The running record. The address field consists of 2 bytes. The content is the address of the program startup and the data field is empty.
The following is an example:
Bytes
S2080108fffffffa
S30800020000000000F5
S5030002FA
S9030000FC line 1: Nothing, just start.
Row 2: The address 0x10000 has four 0xFF
Row 3: Address 0x20000 has 3 0x00
Row 4: indicates that two data records exist.
The fifth line: The program runs the checksum algorithm from the 0x0000 address, which is not the same as intel hex,
Checksum = 0xFF-(total of all bytes starting from the count segment ).
