The flash module contains a built-in signature generator. This generator can produce a
128-bit signature from a range of flash memory. A typical usage is to verify the flashed
contents against a calculated signature (e.g. during programming).
The address range for generating a signature must be aligned on flash-word boundaries,
i.e. 128-bit boundaries. Once started, signature generation completes independently.
While signature generation is in progress, the flash memory cannot be accessed for other
purposes, and an attempted read will cause a wait state to be asserted until signature
generation is complete. Code outside of the flash (e.g. internal RAM) can be executed
during signature generation. This can include interrupt services, if the interrupt vector
table is re-mapped to memory other than the flash memory. The code that initiates
signature generation should also be placed outside of the flash memory.
