3.4.5 SQTP

SQTP (serial quick turn programming) is used to program a unique serial number into each device. This number can be used as an entry code, password or ID number. From the Advanced Mode dialog, click SQTP to display the available settings.

Note: The programmers and tools currently do not support SQTP with serial memory devices. Therefore, the function to import the SQTP file will not be available.

If using SQTP with MPLAB PM3, see “Using SQTP with MPLAB PM3” below for additional information. If using PIC32 devices, see “Using SQTP with PIC32 Devices” below for information on the import methods. For information about how the SQTP files are produced, refer to the SQTP File Format Specification (DS50002539).

Table 3-4. SQTP SETTINGS
Setting	Description
Note: The options available will vary depending on the device and too selected. The following may not show every possible option.
Generation Method:
Random	Select this option to generate unique, random numbers for each part. Also enter the start address, number of bytes and number of parts in the corresponding fields.
Pseudo-Random Seed Value (Hex):	Select this option to generate a pseudo-random set of non-repeating numbers based on the Hex value you enter into the Seed Value field. Also enter the start address, number of bytes and number of parts in the corresponding fields.
Sequential Start Value (Hex): Increment (Dec):	Select this option to generate sequential numbers based on the starting value specified and incrementing each number by the amount specified. Also enter the start address, number of bytes and number of parts in the corresponding fields.
Configuration:
Start Address (Hex)	Enter the starting address (in Hex) for the serial number.
Number of Bytes (Dec)	Enter the size of the serial number (in decimal). Make sure a large enough serial number is specified for the number of parts planned to program using this file.
Number of parts (Dec)	Enter the number of parts to be programmed using this file.
Location:
Program Memory	Select this option to load the SQTP number in program memory.
EEPROM	Select this option to load the SQTP number in EEPROM.
Auxiliary Memory	Select this option to load the SQTP number in auxiliary memory.
User OTP Memory	Select this option to load the SQTP number in One-Time Program memory.
User ID Memory	Select this option to load the SQTP number in user ID memory.
Boot Memory	Select this option to load the SQTP number in boot memory.
Flash Data	Select this option to load the SQTP number in Flash memory.
Access Method:
RETLW	Select this option to use a series of RETLW (Return Literal W) instructions with the serial number bytes as the literal data.
Raw Data	Select this option to use the raw data.
Format for PSV	If the Raw Data option is selected, selecting Format for PSV formats SQTP data to make it compatible with PSV (Program Space Visibility).
Programming Options:
Disable operations of SQTP values are exhausted	Select this option to cease programming if there are no more SQTP values available.
Display the next SQTP sequence in the output window	Select this option to display the information in the output window.
Generate	Click Generate to create the SQTP (.num) file.

Using SQTP with MPLAB PM3

SQTP files for Flash Data memory that were generated prior to MPLAB IPE v2.20 will work with MPLAB PM3 firmware up to v3.00. SQTP file generation for Flash Data memory has been modified to the 32-bit byte order (12345678) and the firmware is updated accordingly. A new SQTP file must be regenerated to work with MPLAB IPE v3.00 and higher.

Using SQTP with PIC32 Devices

For PIC32 devices only, starting with MPLAB IPE v3.15, a dialog box, similar to the one below, is provided to choose either 32-bit byte order (12345678) or 16-bit byte order (56781234) when loading an SQTP file.
