26.10.1.3 Flash Module Status register
26.10.1.4 Flash Module Status Clear register
26.10.2
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.

The FMSTATCLR register is used to clear the signature generation completion flag.

Algorithm and procedure for signature generation
Signature generation
A signature can be generated for any part of the flash contents. The address range to be
used for signature generation is defined by writing the start address to the FMSSTART
register, and the stop address to the FMSSTOP register.
The signature generation is started by writing a ‘1’ to the SIG_START bit in the FMSSTOP
register. Starting the signature generation is typically combined with defining the stop
address, which is done in the STOP bits of the same register.
The time that the signature generation takes is proportional to the address range for which
the signature is generated. Reading of the flash memory for signature generation uses a
self-timed read mechanism and does not depend on any configurable timing settings for
the flash. A safe estimation for the duration of the signature generation is:
Bit
1:0
2
31:3
Bit

Duration = int((60 / tcy) + 3) x (FMSSTOP - FMSSTART + 1)
