Not any datasheet.  For example, this problem is mentioned in the 16C7x
datasheet, but not the 16F87x data sheet because these chips don't have this
problem.

Does anyone have a definative list of which chips have this problem and
which don't?  I'd rather not look thru all the data sheets to find out.
