LOF Fields
The following fields are included in Data I/O’s implementation of the
LOF format:
* These fields are already defined as part of the JEDEC standard and will not be defined in
this section.
<STX> * Start of Data (ASCII Ctrl-B, 0x02 hex)
C * Fuse Checksum
K Fuse data, followed by control words and pulse
link cycles
N * Notes Field
QB Number of bits per word
QC Number of control words at the end of each K
field
QF Number of Fuses in Device (# of K fields)
QM Number of macro cells in the data file
QP * Number of Device Package Pins
QS Number of Hex-ASCII words in each K field
and each control word
QV * Maximum Number of Test Vectors
R Signature Analysis (reserved for future use)
SSpDE Checksum
T Signature Analysis (reserved for future use)
V * Test Vectors (reserved for future use)
X * Default Test Conditions (reserved for future
use)
<ETX> * End of Data (ASCII Ctrl-C, 0x03 hex)

ASCII Octal and Hex Formats, Codes 30-37 and 50-58
Each of these formats has a start and end code, and similar address and
checksum specifications. Figure D-6 illustrates 4 data bytes coded in each
of the 9 ASCII Octal and Hexadecimal formats. Data in these formats are
organized into sequential bytes separated by the execute character (space,
percent, apostrophe, or comma). Characters immediately preceding the
execute character are interpreted as data. ASCII Octal and Hex formats
can express 8-bit data, by 3 octal or 2 hexadecimal characters. Line feeds,
carriage returns, and other characters may be included in the data stream
as long as a data byte directly precedes each execute character.

D-20 ProMaster 2500 User Manual
Although each data byte has an address, most are implied. Data bytes are
addressed sequentially unless an explicit address is included in the data
stream. This address is preceded by a $ and an A, must contain 2 to 8 hex
or 3 to 11 octal characters, and must be followed by a comma, except for
the ASCII-Hex (Comma) format, which uses a period. The programmer
skips to the new address to store the next data byte; succeeding bytes are
again stored sequentially.
Each format has an end code, which terminates input operations.
However, if a new start code follows within 16 characters of an end code,
input will continue uninterrupted. If no characters come within 2
seconds, input operation is terminated.
After receiving the final end code following an input operation, the
programmer calculates a sumcheck of all incoming data. Optionally, a
sumcheck can also be entered in the input data stream. The programmer
compares this sumcheck with its own calculated sumcheck. If they
match, the programmer will display the sumcheck; if not, a sumcheck
error will be displayed.
Note: The sumcheck field consists of either 2-4 hex or 3-6 octal characters,
sandwiched between the $ and comma characters. The sumcheck
immediately follows an end code. The sumcheck is optional in the input
mode but is always included in the output mode. The most significant
digit of the sumcheck may be 0 or 1 when expressing 16 bits as 6 octal
characters.
The programmer divides the output data into 8-line blocks. Data
transmission is begun with the start code, a nonprintable STX character,
or optionally, SOH.* Data blocks follow, each one prefaced by an address
for the first data byte in the block. The end of transmission is signaled by
the end code, a nonprintable ETX character. Directly following the end
code is a sumcheck of the transferred data.
* ASCII-Octal SMS and ASCII-Hex SMS use SOM (CTRL-R) as a start code and EOM
(CTRL-T) as an end code.
