7.5.5.2 MANUAL DOWNLOAD

It is recommended that MPLAB PM3 automatically detect and notify of any upgrades.

Normally, it is not necessary to manually update the OS Suite for the MPLAB PM3

programmer; however, if you need to revert to an earlier OS Suite version, select

Programmer>Settings

and click on the Configuration tab. Then, click the Manual

Download button. If this option is selected, the system will prompt with an auto update

notice (Figure 7-9). To continue with the download, click Yes, or click No to cancel.

FIGURE 7-9: MANUAL DOWNLOAD

Clicking Yes opens a Browse window to select the appropriate file from the MPLAB IDE

directory. The format of the OS Suite file is pm3nnnnnn.mjc, where nnnnnn is the OS

Suite version.

7.6 SPECIAL PROGRAMMING

7.6.1 Using SQTP

Serialization of devices is done by using a series of RETLW (Return Literal W)

instructions, with the serial number bytes as the literal data. To serialize, first generate

a serialization file, and then use that file to serialize locations in the device

microcontroller. Using SQTP includes these steps:

• Generating the SQTP File

• Activating Serialization

• Programming the Device

Refer to Section 7.7.1 “Using Hexadecimal Record Formats” for more information

on hex record formats.
