Ouch, that is an errata I wouldn't want. To me it suggests that you will mi=
ss codes where the 5 LSB are all ones, i.e. it will go from xxxxxx011110  t=
o xxxxxx100000, or else it goes from xxxxx011111 to xxxxx100001, in each ca=
se it jumps over a value.

Depending on just what you are doing this may not matter.
