All tool programmers must perform a common set of
steps, regardless of the actual method being used.
Figure 3-1 shows the set of steps to program PIC32MX
devices.

Note:
Note:
Connect to the Target Device.
To ensure successful programming, all required
pins must be connected to appropriate signals.
See 4.0 “Connecting to the Device” in this
document for more information.
Place the Target Device in Programming Mode.
For 2-wire programming methods, the target
device must be placed in a special programming
mode (Enhanced ICSP™) before executing any
other steps.
See 7.0 “Entering Programming Mode” for
more information.
Check the Status of the Device.
Step 3 checks the status of the device to ensure
it is ready to receive information from the
programmer.
See 8.0 “Check Device Status” for more
information.
Erase the Target Device.
If the target memory block in the device is not
blank, or if the device is code-protected, an
erase
programming any new data.
See 9.0 “Erasing the Device” for more
information.
Enter Programming Mode.
Step 5 verifies that the device is not code-
protected and boots the TAP controller to start
sending and receiving data to and from the
PIC32MX CPU.
See 10.0 “Entering Serial Execution Mode”
for more information.
Download the Programming Executive (PE).
The PE is a small block of executable code that
is downloaded into the RAM of the target device.
It will receive and program the actual data.
See 11.0 “Downloading the Programming
Executive (PE)” for more information.
Download the Block of Data to Program.
All methods, with or without the PE, must down-
load the desired programming data into a block
of memory in RAM.
See 12.0 “Downloading a Data Block” for
more information.
For the 4-wire programming methods,
Step 2 is not required.
If the programming method being used
does not require the PE, Step 6 is not
required.
