Harlan -

There was a problem with a mask set that the internal clock would not trim to the 25.6 MHz option. These parts are marked with the '1'.  Parts that will trim correctly at 25.6 MHz are marked with '2'.

If you are using an external crystal or if you are using the internal at 4, 8, or 12.8 MHz, then this won't make a difference.
