Motorola EXORmacs Format, Code 87

Motorola data files may begin with an optional sign-on record, initiated

by the start characters S0. Data records start with an 8- or 10-character

prefix and end with a 2-character suffix. Figure D-14 shows a series of

Motorola EXORmacs data records.

Each data record begins with the start characters S1 or S2: S1 if the

following address field has 4 characters, S2 if it has 6 characters. The third

and fourth characters represent the byte count, which expresses the

number of data, address, and checksum bytes in the record. The address

of the first data byte in the record is expressed by the last 4 characters of

the prefix (6 characters for addresses above hexadecimal FFFF). Data

bytes follow, each represented by 2 hexadecimal characters. The number

of data bytes occurring must be 3 or 4 less than the byte count. The suffix

is a 2-character checksum, the one’s complement (in binary) of the

preceding bytes in the record, including the byte count, address, and data

bytes.

The end-of-file record begins with an S9 start character. Following the

start characters are the byte count, the address, and a checksum. The

maximum record length is 250 data bytes.

Intel MCS-86 Hexadecimal Object, Code 88

The Intel 16-bit Hexadecimal Object file record format has a 9-character

(4-field) prefix that defines the start of record, byte count, load address,

and record type and a 2-character checksum suffix. Figure D-15 shows a

sample record of this format.

The four record types are described below.

Figure D-15

An Example of Intel MCS-86 Hex Object

00-Data Record

This begins with the colon start character, which is followed by the byte

count (in hex notation), the address of the first data byte, and the record

type (equal to 00). Following these are the data bytes. The checksum

follows the data bytes and is the two’s complement (in binary) of the

preceding bytes in the record, including the byte count, address, record

type, and data bytes.

01-End Record

This end-of-file record also begins with the colon start character. This is

followed by the byte count (equal to 00), the address (equal to 0000), the

record type (equal to 01), and the checksum, FF.

02-Extended Segment

Address Record

This is added to the offset to determine the absolute destination address.

The address field for this record must contain ASCII zeros (Hex 30s).

This record type defines bits 4 to 19 of the segment base address. It can

appear randomly anywhere within the object file and affects the

absolute memory address of subsequent data records in the file. The

following example illustrates how the extended segment address is used

to determine a byte address.

:10000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF00

:10001000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF0

:10002000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFE0

Problem:

Find the address for the first data byte for the following file.

:02 0000 02 1230 BA

:10 0045 00 55AA FF.....BC

Solution:

Step 1. Find the record address for the byte. The first data byte is 55.

Its record address is 0045 from above.

Step 2. Find the offset address. The offset address is 1230 from

above.

Step 3. Shift the offset address one place left, then add it to the

record address, like this:

1230

Offset address (upper 16 bits)

+ 0045

Record address (lower 16 bits)

12345

20-bit address

The address for the first data byte is 12345.

Note: Always specify the address offset when using this format, even when the

offset is zero.

During output translation, the firmware will force the record size to 16

(decimal) if the record size is specified greater than 16. There is no such

limitation for record sizes specified less than 16.

03-Start Record

This record type is not sent during output by Data I/O translator

firmware.
