You can perform a Blank Check by selecting Programmer>Blank Check All from the
MPLAB PM3 menu. This check will verify that the device is completely blank (all bits
are set to a ‘1’) and all Configuration bits are set to a ‘1’ (unprogrammed state).
If you are using a One-Time Programmable (OTP) device, some Configuration bits
(e.g., oscillator bits) might have already been programmed at the factory. Make sure
the Configuration bits are set to the factory settings and select Programmer>
Blank Check OTP. This will check that all program memory bits are set to ‘1’, and that
the Configuration bits match the value in the dialog. An OTP device cannot be erased
and reprogrammed.
If the EPROM device is not blank, you will have to erase it before programming, or
select another device:
1. Remove any labels covering the device window. If you do not have a windowed
