These registers control automatic signature generation. A signature can be generated for
any part of the flash memory contents. The address range to be used for generation is
defined by writing the start address to the signature start address register (FMSSTART)
and the stop address to the signature stop address register (FMSSTOP. The start and
stop addresses must be aligned to 128-bit boundaries and can be derived by dividing the
byte address by 16.
Signature generation is started by setting the SIG_START bit in the FMSSTOP register.
Setting the SIG_START bit is typically combined with the signature stop address in a
single write.
Table 873
registers respectively.
The signature generation result registers return the flash signature produced by the
embedded signature generator. The 128-bit signature is reflected by the four registers
FMSW0, FMSW1, FMSW2 and FMSW3.
The generated flash signature can be used to verify the flash memory contents. The
generated signature can be compared with an expected signature and thus makes saves
time and code space. The method for generating the signature is described in
Section
Table 878
respectively.
