S / N mode
S / N mode option defines the form in which serial value has to be written to buffer. Two
options are available:
ASCII
Bin
ASCII - means the serial number is written to buffer as ASCII string. For example number
$0528CD is in ASCII mode written to buffer as 30h 35h 32h 38h 43h 44h (‘0’ ‘5’ ‘2’ ‘8’ ‘C’ ‘D’),
i.e. six bytes.
Bin - means the serial number is written directly to buffer. If the serial number has more than
one byte length, it can be written in one of two possible byte orders. The byte order can be
changed in „Save to buffer“ item.
Style
Style option defines serial number base. There are two options:
Decimal
Hexadecimal.
Decimal numbers are entered and displayed using the characters '0' through '9'.
Hexadecimal numbers also use characters 'A' through 'F'.
The special case is Binary Dec, which means BCD number style. BCD means the decimal
number is stored in hexadecimal number, i.e. each nibble must have value from 0 to 9. Values
A to F are not allowed as nibbles of BCD numbers.
Select the base in „Style“ options before entering numbers of serial start value and step.
Save to buffer
Save to buffer option specifies the serial value byte order to write to buffer. This option is used
for Bin S / N mode (for ASCII mode it has no effect).
Two options are available:
LSByte first (used by Intel processors) will place the Least Significant Byte of serial number
to the lowest address in buffer.
MSByte first (used by Motorola processors) will place the Most Significant Byte first to the
lowest address in buffer.
Split serial number
The option allows dividing serial number into individual bytes and placing the bytes at each Nth
address of buffer. This feature is particularly useful for SQTP serialization mode for Microchip
PIC devices when the device serial number can be the part of program memory as group of
RETLW or NOP instructions. For more information see Example 2 shown in Examples section
below.
Following split options are available:
Check box Split serial number – turns on/off split function
Split gap – specifies number of bytes placed between split serial number fragments
S/N fragment size – serial number is split into fragments with size specified by this option
Example 1:
Write serial numbers to AT29C040 devices at address 7FFFAH, size of serial number is 4
bytes, start value is 16000000H, incremental step is 1, the serial number form is binary and
least significant byte is placed at the lower address of serial number in device.
