Note:
The default setting values refer to the factory configuration. The factory configuration can be overwritten by the user in accordance
with the target application requirements.
The factory configuration values are loosed after user programming fields or in case of the ROP unprotecting attempt causing
a “Global Flash Erase”.
The predefined initialized bit-values (1 or 0) must be preserved during memory writing.
An undefined option bit must be keep 0 and the complement value at 1 during the memory writing sequence.
