| − | The STM32F0 series devices have different levels of read protection. The level of read protection has to be specified in the RDP byte which is part of the option bytes at address 0x1FFFF800. A special sequence, consisting of different read / write accesses to special function registers of the MCU are required to change the value of the RDP byte (examples below). |
