Burn Failed Error:
The error message shown in Figure 29 occurs only during a failed program attempt. Here, the value that is
programmed into the associated register does not match the value that was entered into that registers dialog box
prior to executing the programming operation. The most likely cause of this error is a missed enable or disable step
during the programming procedure. Other causes could be a communication error that would also prompt Picor
Buck GUI to report the appropriate error. If this error occurs after receiving the “Missing or Malfunctioning I2C
Interface Error”, it is critically important to ensure that you shut down power to the PI33XX-2X and exit the Picor
Buck GUI prior to attempting to reprogram again. Adhering to this step can possibly avoid programming the wrong
register values.

Burn Skipped Error:
The error message shown in Figure 30 occurs only when the user has attempted to program a value into an
associated register that was previously programmed. The burn process will be terminated and the user will be
returned to the main menu.
