32.10.1.3 Flash Module Status register (FMSTAT - 0x0x4008 4FE0)
The read-only FMSTAT register provides a means of determining when signature
generation has completed. Completion of signature generation can be checked by polling
the SIG_DONE bit in FMSTAT. SIG_DONE should be cleared via the FMSTATCLR
register before starting a signature generation operation, otherwise the status might
indicate completion of a previous operation.
32.10.1.4 Flash Module Status Clear register (FMSTATCLR - 0x0x4008 4FE8)
The FMSTATCLR register is used to clear the signature generation completion flag.
