Figure 10–12. Motorola-S Format
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
S0
S1
S2
S3
S7
S8
S9
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.
Figure 10–12 illustrates the Motorola-S object format.
