40.11.1.3
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.

Reset Value
31:2 -
Reserved, user software should not write ones to reserved bits. The value read NA
from a reserved bit is not defined.
2
SIG_DONE
When 1, a previously started signature generation has completed. See
0
FMSTATCLR register description for clearing this flag.
1:0 -
Reserved, user software should not write ones to reserved bits. The value read NA
from a reserved bit is not defined.
40.11.1.4 Flash Module Status Clear register (FMSTATCLR - 0x0x4008 4FE8)
The FMSTATCLR register is used to clear the signature generation completion flag.

2
SIG_DONE_CLR Writing a 1 to this bits clears the signature generation completion flag
0
(SIG_DONE) in the FMSTAT register.
1:0 -
Reserved, user software should not write ones to reserved bits. The value read NA
from a reserved bit is not defined.
