UnInit

int UnInit (
  unsigned long fnc);            /* Function code */

The UnInit function de-initializes the microcontroller and is invoked at the end of an erasing, programming, or verifying step.

The UnInit function has a parameter fnc:

• 1 - stands for Erase.
• 2 - stands for Program.
• 3 - stands for Verify.

Thus, different de-initialization sections can be implemented for each individual Flash programming step.

The UnInit function returns a value:

• 0 - on success.
• 1 - on failure.

Init

int UnInit (unsigned long fnc) {

  // Lock Flash
  FLASH->CR |=  FLASH_LOCK;

  return (0);
}
