S-RECORD TYPES

Eight types of S-records have been defined to accommodate the several needs of

the encoding, transportation, and decoding functions. The various Motorola

upload, download, and other record transportation control programs, as well as

cross assemblers, linkers, and other file creating or debugging programs,

utilize only those S-records which serve the purpose of the program. for

specific information on which S-records are supported by a particular program,

the user manual for that program must be consulted.

NOTE

The EVB monitor supports only the S1 and S9 records. All data before the first

S1 record is ignored. Thereafter, all records must be S1 type until the S9

record terminates data transfer.

An S-record format may contain the following record types:

S0 Header record for each block of S-records. The code/data field may

contain any descriptive information identifying the following block

of S-records. The address field is normally zeroes.

S1 Code/data record and the 2-byte address at which the code/data is to

reside.

S2-S3 Code/data record is 3 or 4 byte address. Not supported by monitor.

S7-8 Termination record for a block of S2 or S3 records.

S9 Termination record for a block of S1 records. Address fields may

optionally contain the 2-byte address of the instruction to which

control is to be passed. If not specified, the first entry point

specification encountered in the input will be used. There is no

code/data field.

Only one termination record is used for each block of S-records. Normally, only

one header record is used, although it is possible for multiple header records

to occur.

S-RECORD CREATION

S-record format programs maybe produce by several dump utilities, debuggers, or

several cross assemblers or cross linkers. Several programs are available for

downloading a file in S-record format from a host system to an 8-bit or 16-bit

microprocessor-based system.
