I think the offset is wrong and the lengths need to be initialize to 0 too, as a precautionary case .. in the case if the shifts are not equal to the number of bit positions. In the library this does not matter, as those shifts exactly matches the fields and the error is avoided there .. Else we would have been debugging in the library .. Anyway hope to catch some bugs there too .. Manu
