Locking mechanism
The advanced timers registers and bits can be protected or locked in order to safeguard the
application using the locking mechanism by programming the LOCK bits in the BDTR
register. There are three locking levels.
Note:
The LOCK bits can be written only once after the reset. Once the BDTR register has been
written, its content is frozen until the next reset.
