+ (#) The PcROP sector is selected by using the same option bytes as the Write
+ protection (nWRPi bits). As a result, these 2 options are exclusive each other.
+ (#) In order to activate the PcROP (change the function of the nWRPi option bits),

+ is read/write protected.
+ (#) To activate PCROP mode for Flash sector(s), you need to call the following function:
