5.3.1 Recently Used

Select “Recently Used” to retrieve the last device used in MPLAB PM3. This option dis-

plays the seven most recently used devices and enables quick access to the Command

menu for the device.

5.3.2 Select Device

Select “Select Device” to indicate the device family and then, the device that is to be

programmed. After the device is selected, MPLAB PM3 will display the Command

Menu with commands that are applicable to the device type and its features, such as

Program/Verify Device, Verify Device and All Functions.

5.3.2.1 PROGRAM/VERIFY DEVICE

Select “Program Verify Device” to program the device in the socket module with the hex

file that was previously loaded into the internal memory of the device programmer. This

is referred to as the image. If the hex file has not been loaded, the system displays a

message stating “Valid image not present! Please download an image or use a master

device before continuing”. Download the hex file desired for programming the device

into MPLAB PM3 before attempting to continue.

The device programmer checks to see if the installed microcontroller device is blank. If

the device is not blank, the device programmer asks if you want to continue. Answer

“Yes” to continue. Answer “No” to return to the Command menu.

If a flash device is in use, the device will immediately be programmed with the image

in the MPLAB PM3. If a One-Time Programmable (OTP) device is being used and the

Blank Check Override is enabled on MPLAB PM3, two options (Stop Programming and

Continue) will display if the device is not blank. Select “Stop Programming” if you do not

wish programming to continue. Otherwise, select “Continue” and the device will be pro-

grammed.

MPLAB PM3 programs the image of the hex file into the microcontroller device con-

nected to the programmer.
