Note:
  1. Fresh from factory value or after a ChipErase_ALL command.
  2. The PAC Peripheral is always secured if BOCOR.SECCFGLOCK = 1 after exiting the Boot ROM.
  3. The IDAU peripheral is always secured regardless of its bit value.
  4. The NVMCTRL Peripheral is always secured if BOCOR.SECCFGLOCK = 1 after exiting the Boot ROM
  5. The DSU peripheral is always non-secured regardless of its bit value.
  6. Secure Flash (AS region) = Secure Flash (APPLICATION region) + Non-Secure Callable Flash (APPLICATION region)
CAUTION:
  1. BOD12 and BOD12PLL are calibrated in production and their calibration parameters must not be changed to ensure the correct device behavior.
