Access protection
This bit, if programmed at 0, disables any access (read/write) to data mapped
inside IFlash module address space, unless the current instruction is fetched from
IFlash.
Debug protection
This bit, if erased at 1, can be used to by-pass all the protections using the debug
features through the test interface. If programmed at 0, on the contrary, all the
debug features, the test interface and all the Flash test modes are disabled. Even
STMicroelectronics will not be able to access the device to run any eventual failure
analysis.

Write protection bank 0/sectors 7-0 (IFlash)
