MPLAB PM3 ENVIRONMENT
The MPLAB PM3 device programmer uses a new concept called an MPLAB PM3
Environment. An Environment is a snapshot of the current programming settings for a
specific device. It contains all the necessary information to recreate the current
programming state, including a binary image of the device’s memory data, links to an
optional SQTP file, specific part information and optional miscellaneous files.
When an Environment is saved, a directory is created on the removable MPLAB PM3
Card (an SD-MMC memory card), on the selected drive on a PC or another storage
device. The name of the directory created is the same as the name given to the
Environment file. Figure 6-1 illustrates the layout of an Environment.
As an introduction to environments, this covers:
• Creating an MPLAB PM3 Environment on the MPLAB PM3 Card
• Loading an MPLAB PM3 Environment into the MPLAB PM3 programmer
There are additional operations, such as viewing, copying and deleting Environments.
Refer to Chapter 9. “MPLAB PM3 Card Reference” for specific instructions for each
of these operations.

LAYOUT OF AN ENVIRONMENT
An Environment is the encapsulation of the environment file (*.pm3), the binary bin file
(*.bin), optional SQTP num file (*.num) and miscellaneous files.
The PM3 file (*.pm3) is a part of the Environment. It is the high-level file that contains
MPLAB PM3's settings, name of the bin file and name of the SQTP file.
The device’s image (binary file) is the data that should be programmed into the device.
It is the same continuous data chunk that is sent between MPLAB IDE and
MPLAB PM3 during a standard operation. Error detection mechanisms are also
attached.
