Note:
Flash Write/Erase Protection Register
The Flash Write/Erase Protection register prevents accidental Write or Erase operations.
The protection is limited to a resolution of eight 16 KB blocks. Setting a bit to 1 protects
that 16 KB block of Flash memory from accidental writing or erasure. Default on RESET
is for all Flash memory blocks to be protected.
Writes to this register are allowed only after it is unlocked via the FLASH_KEY register.
Any attempted Writes to this register while locked sets it to
blocks.
