FIGURE 2-13:
2.7.1
If a device has EEPROM data memory, the “Enabled” checkbox next to Program
Memory and EEPROM Data will become available.
The checkboxes select which memory regions’ programming operations will be
affected. Refer to Table 2-1 for a description of how programming operations are
affected by the checkboxes. Erase and Blank Check always operate on all memory
regions.
TABLE 2-1:
During a Write, regions that are unchecked will remain unchanged in the device.
For example, if Program Memory is unchecked while EEPROM Data is checked, then
a Write operation will only write EEPROM Data, while Program Memory, User IDs and
Configuration Words in the device will remain unchanged.
If Program Memory is checked while EEPROM Data is unchecked, then a Write
operation will program Program Memory, User IDs and Configuration Words, while
EEPROM Data in the device will remain unchanged.
Due to programming constraints in some devices, the PICkit 2 Programmer application
may read and re-write EEPROM data memory during a Write to preserve it.
It is not allowed to have both memory regions unchecked.
2.7.2
Prior to each Write, the imported hex file time stamp is compared to the version on the
disk. If the version on the disk is newer, it is reloaded. This occurs only when a hex file
has been read from the disk.
This feature ensures that the latest version built will be written to the device. It may be
used with the Tools>Program on PICkit Button feature to program the latest MPLAB
IDE build without switching to the PICkit 2 Programmer software simply by pressing the
PICkit 2 unit push button.
