MCF5213 66Mhz vs 80Mhz

Hello All
 
I am currently working on a design based on MCF5213CAF66, if
I were to replace this with the 80Mhz version (MCF5213CAF80
) which seems to  be pin compatible, is there any special
precaution I need to take care of? i.e. interms of crystal
stuff or codewise changes?
 
Thansk for your comments.

Hello Jay,

I change from 5282 64Mhz to a 5282 with 80Mhz. On the
hardware side I use a
8 Mhz crystal (formerly 4 MHz). After that you should
re-program the PLL.
All what depends from the sys-clock, runs faster (Timer,
CAN, SPI and so
on).

Regards Joerg
