4.1 OTP Programming

1. Keep the jumper J12 connected on the KITPF1550FRDMPGM socket board
2. Place a blank PF1550 part in the socket, and ensure that the chip #1 pin matches the socket marked corner

3. Connect mini-USB cable between FRDM-KL25Z FRDM board and PC, then the “Device connected” prompt in KITPF1550GUI shows good connection

4. Select the checkbox Click to Enable Target:

5. Copy the script generated in PF1550 OTP Programming Request Form to the “Script Editor” tab in the GUI. Click Save Script to save to txt file for future loading

6. Click Run Script to run the OTP programming until the following message is displayed "OK: programming voltage off”. The red LED D2 turns ON, indicating that the programming is in process
7. Click Verify OTP Values to view the OTP register values of the programmed part
8. Remove and reconnect jumper J12, then switch to “OTP Configuration” tab to view the PF1550 programmed part start-up sequence

9. Unplug the mini-USB cable to continue OTP programming for the next new blank part (repeat steps 2 to 7)
