Using MPLAB PM3 in Stand-Alone Mode

Programming is performed at the VDD Applied, the VDD minimum and maximum volt-

ages (OTP devices) or V

DD Nominal that has been established as the default per oper-

ating range for the device. See Section 8.5.3.7.3 “Adjust Voltages” if the verification

needs to be performed at different voltage settings. Verification of the device against

the MPLAB PM3 image occurs immediately after programming, along with the display

of the resulting checksum if both have been successful.

If errors occur during programming or verification, the first address of each memory

area that failed will be reported on the LCD.

5.3.2.2 VERIFY DEVICE

Select “Verify Device” to compare the contents of the device to that of the MPLAB PM3

memory (image). This comparison is performed at the V

DD Applied, VDD minimum and

maximum voltage (OPT devices) or V

DD Nominal that has been established as the

default per the operating range for the device. See Section 8.5.3.7.3 “Adjust Volt-

ages” if the verification needs to be performed at different voltage settings.

If the content of the device matches the MPLAB PM3 image, the message “Passed!”

and the resulting checksum are displayed on the LCD. If not, the first address of each

memory area that failed will be reported on the LCD.

5.3.2.3 READ DEVICE

Select “All Functions” then “Read Device” to retrieve the contents of the device and

place it into the MPLAB PM3 memory. This image can then be used to program suc-

cessive devices with the same information or the information can be code-protected

then used for programming.

If the device is code-protected, a message stating that the device is code-protected will

be displayed on the LCD and the contents will not be placed into the MPLAB PM3

memory. However, the resulting checksum will be included in the display if this option

has been enabled in the Programmer Settings.

If the device is not code-protected, the contents will be placed into the MPLAB PM3

memory. Two options (No and Code Protect All?) will be displayed on the LCD along

with the resulting checksum. Select “No” if code protection of the current or successive

devices in not desired. Otherwise, select “Code Protect All?” if code protection of the

current or successive devices is desired.

After selecting either code protection option, the display returns to the “Read Device”

option. Press the <ESC> key to return to the Command menu for the device. If code

protection was selected, “Program Verify Device” must be used to program the current

or successive devices with the code-protected image in the MPLAB PM3 memory.

5.3.2.4 ALL FUNCTIONS

Select “All Functions” to display all of the stand-alone commands that are applicable to

programming, reading, verifying and displaying the status of the currently selected

device. See Section 8.5.3 “All Functions” for details on each of the options that may

be available for the device.
