Hi

From my curiosity,
can you please clarify your criteria regarding which fields of a register should be signed or unsigned?
I guessed that the fields marked with FTR_LOWER_SAFE or FTR_HIGHER_SAFE could be unsigned,

Also, the unsigned values are not restricted to LOWER_SAFE/HIGHER_SAFE, but also applies for
FTR_EXACT, so that we use the appropriate methods to extract them.
