Description of the Object Formats
10-41 Hex Conversion Utility Description
10.11.3 Motorola Exorciser Object Format (–m1, –m2, –m3 Options)
The Motorola S1, S2, and S3 formats support 16-bit, 24–bit, and 32–bit
addresses, respectively. The formats consist of a start-of-file (header) record,
data records, and an end-of-file (termination) record. Each record is made up
of five fields: record type, byte count, address, data, and checksum. The
record types are:
Record Type Description
S0 Header record
S1 Code/data record for 16–bit addresses (S1 format)
S2 Code/data record for 24–bit addresses (S2 format)
S3 Code/data record for 32–bit addresses (S3 format)
S7 Termination record for 32–bit addresses (S3 format)
S8 Termination record for 24–bit addresses (S2 format)
S9 Termination record for 16–bit addresses (S1 format)
The byte count is the character pair count in the record, excluding the type and
byte count itself.
The checksum is the least significant byte of the 1s complement of the sum
of the values represented by the pairs of characters making up the byte count,
address, and the code/data fields.
