Controlling the PGA450-Q1 Memory Spaces With the GUI
8.5.3 Verify OTP Programming
If the Verify OTP Programming button was also checked (default), then after the OTP memory is finished
programming, the GUI reads the contents of the OTP memory through SPI and verifies against the .HEX
file. If the OTP memory matches the contents of the .HEX file, the GUI displays the message "OTP
Memory Verification Successful," as seen in
Figure 7. OTP Memory Successful Programming Verification
8.5.4 Check OTP Status
Press the "Check OTP Status" button to verify what is currently programmed into OTP. The three possible
results are:
• Programmed to Jump to DEVRAM: The jump to DEVRAM statement has been programmed into the
OTP. This means that programs loaded into the DEVRAM will execute.
• OTP Empty: Nothing has been programmed in the OTP.
• Programmed: The OTP has been programmed with something other than the jump to DEVRAM
statement.
