When set, this bit protects flash addresses from 0 to BOOT_SIZE*1024 from flash page erase.
The WD overflow status bit. This bit is set when the WD timer overflows. It is powered
by the nonvolatile supply and at bootup will indicate if the part is recovering from a WD
overflow or a power fault. This bit should be cleared by the MPU on bootup. It is also
automatically cleared when RESET is high.
When set, this bit protects flash addresses from CE_LCTN*1024 to the end of memory
from flash page erase.
An 8-bit value has to be written to this address prior to accessing the RTC registers.
