8.5 COMMAND MENU

After a device is selected, the device programmer displays the Command menu:

• Program Verify Device

• Verify Device

• All Functions

The functions on the Command menu allow you to perform the basic user tasks for

programming a microcontroller device. Pressing <ESC> repeatedly will return you to

the Main menu.

8.5.1 Program Verify Device

The Program Verify Device option erases (if Flash device), programs and verifies the

device (see Section 8.5.3.7 “Settings”).

8.5.2 Verify Device

The Verify Device option verifies that the device was programmed properly.

8.5.3 All Functions

The All Functions option displays a submenu with the selections listed in Table 8-1:

8.5.3.1 READ DEVICE

If you want to copy firmware from a programmed device into an unprogrammed device,

you can read the programmed firmware into MPLAB PM3 memory, then program the

new device based on this information. Select “Read Device” to copy the contents of the

device in the socket module into the internal memory of the device programmer.

For PIC16CXX devices, the device programmer will ask the question: “Code Protect

Parts?” Answer “Yes” to code-protect the parts that you will be programming. Code

protection will remain effective until a new device is read. Answer “No” to program

devices exactly as read.

After reading a device, the device programmer displays a checksum. If the device is

code-protected, a code protection message will be displayed prior to the read. Answer

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

TABLE 8-1: ALL FUNCTIONS MENU

Selection Description

Read Device Reads the device content. Selective read (e.g., part of program

memory, only Configuration bits of the device) can be done by

setting up Settings below.

Program Verify Device Programs and verifies the device.

Verify Device Verifies that the device was programmed properly.

Blank Check Device Checks that the device is completely blank (all bits are set to ‘1’).

This will also check that all Configuration bits are set to ‘1’

(unprogrammed state).

Erase Device Erases the device in the MPLAB

PM3 device programmer. This

option displays only for erasable devices.

Device Information Displays the device name, Device ID, Device Revision, Last

Checksum and the User IDs.

Settings Sets up program/verify options, ICSP™ settings, adjust voltages,

reset voltages, reset statistics count and safe mode.
