DEVICE ID OPTION (BETA)
This option checks that the selected device is inserted in the socket module. When you
select this menu option, a message appears asking if you want to check device IDs,
states the current setting and offers two options (see Figure 8-3).

The default setting is “Don’t Test Device Ids” (“Currently: No”). The setting is saved
when the programmer is powered off.
Selecting the “Test Device Ids” option verifies that the device selected through
MPLAB PM3 matches the device installed in the socket module. This is helpful in avoid-
ing programming the wrong device. The “Currently:” display changes to Yes when the
“Test Device Ids” option is set.

BLANK CHECK OVERRIDE
Selecting this option disables the Blank Check from occurring before programming an
EEPROM or ‘C’ device. When you select this menu option, a message appears asking
if you want to override the Blank Check, states the current setting and offers two

The default setting is “Blank Check ‘C’ devices” (“Currently: Yes”). The setting is saved
when the programmer is powered off.
Selecting the “Override Blank Check” enables programming C devices without first
checking that they are blank. The “Currently:” display changes to No when the
“Override Blank Check” option is set.
This setting is used if the C device is preprogrammed, for example, with oscillator val-
ues. In that case, if you performed a Blank Check, the device would fail because
MPLAB PM3 would detect the preprogrammed settings. Using the override setting is
helpful in those situations.
