How do we decode the third line of the QFN48 marking codes for Freescale (NXP) S08 QE microcontrollers?

Is there a document that specifies these markings?

We are specifically interested in the lot numbers and / or date codes.


The device in question is:

 Base Part Number MC9S08QE128

 Complete Part Number MC9S08QE128CFT 

 Mask Set 3M11J

 Package QFN48


Examples of the codes in question are CTAKEMA, CTBEFJB, CTBBEXA
