Checking For a Blank Device
Insert the device to be programmed into the PRO MATE II socket. Position pin
one on the device to be in the pin one position as shown on the diagram next
to the socket. Secure the device by pushing down the silver lever on the
socket.
Click on Blank in the PRO MATE Device Programmer dialog to verify that the
device is completely blank (all bits are set to a “1”). This will also verify that all
configuration bits are set to a “1” (unprogrammed) state. You can also perform
a blank check from PRO MATE II > Blank Check All.
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.
Set the configuration bits to the factory settings and select PRO MATE II >
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 use another device. To erase a windowed device:
If the device is EEPROM/FLASH, you do not have to erase it before
reprogramming it. These devices are electrically erased before programming.

time required to completely erase a UV erasable device depends on:

the process technology of the device (the size of the memory cells).
