Hi All

I am a little confused as to the maximum bus frequency quoted on the M5221X Product Summary Page:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MCF5221X&nodeId=0162468rH3YTLC00M95448&tab=Buy_Parametric_Tab&fromSearch=false

The M5221X types are given to have 25MHz to 40MHz maximum bus speed.
In the data sheets and user manual the values of 50MHz to 80MHz are specified.

[As a comparison - the M5222X are specified on the product summary page to have max. bus speed of 80MHz, corresponding to the same value of 80MHz as specified in the data sheet].

Is this an error or a different interpretation?

Regards
