PICkit 2 Programmer Getting Started
2.8
VERIFYING THE DEVICE
The Verify function verifies that the program in device memory matches the hex file
imported into the PICkit 2 Programmer application. It compares all areas of memory
including program memory, data EEPROM memory, ID and Configuration bits.
To verify the code, import the hex file and click Verify (Figure 2-14).
Note that a Write operation is automatically verified if Programmer>Verify on Write is
checked.
FIGURE 2-14:
BUTTONS - VERIFY
If the code is the same, the status bar turns green and displays “Device Verified”. If a
discrepancy is found, the status bar turns red and displays where the error is located:
“Error in Program Memory, Data EEPROM Memory, or Configuration Bits”.
Table 2-1 illustrates how Verify is affected by the memory region checkboxes.
2.9
READING DEVICE MEMORY
To view the code written to the device, click Read (Figure 2-15).
FIGURE 2-15:
BUTTONS - READ
The code is displayed in the Program Memory and EEPROM Data windows for your
review. If all zeros are displayed, it is possible that the device is code-protected (See
Section 2.10 “Code Protecting the Device” .)
Table 2-1 illustrates how Read is affected by the memory region checkboxes.
2.10
CODE PROTECTING THE DEVICE
The Code and Data Protect functions enable the read protection features of the device.
To protect the program memory code, complete the following steps:
1. Import hex file.
2. Select Tools>Enable Code Protect as shown in Figure 2-16.
3. Click Write .
Devices that have EEPROM data memory may protect it by selecting Tools>Enable
Data Protect .
