NAME

srec_mos_tech - MOS Technologies file format

DESCRIPTION

The Mos Technologies format allows binary files to be uploaded and downloaded between between a computer system (such as a PC, Macintosh, or workstation) and an emulator or evaluation board for microcontrollers and microprocessors.

The Lines

Each line consists of 5 fields. These are the length field, address field, data field, and the checksum. The lines always start with a semicolon (;) character.

The Fields

; Length Address Data Checksum
Length
The record length field is a 2 character (1 byte) field that specifies the number of data bytes in the record.
Address
This is a 2-byte address that specifies where the data in the record is to be loaded into memory.
Data
The data field contains the executable code, memory-loadable data or descriptive information to be transferred.
Checksum
The checksum is an 2-byte field that represents the least significant two byte of the the sum of the values represented by the pairs of characters making up the record's length, address, and data fields.

Size Multiplier

In general, binary data will expand in sized by approximately 2.4 times when represented with this format.

EXAMPLE

Here is an example MOS Technologies format file. It contains the data ``Hello, World'' to be loaded at address 0.
