MC9S12DT256 Mask set Number 4L91N and 0L01Y, what is the difference  between them? If my chip with  mask set 4L91N doesn't work, can replace it with one marked 0L01Y ?

Maskset errata documents describe what's different. So just take them and compare yourself.

It seems have no difference between them. Any official guy can confirm it?
