MCF52259 RTC Crystal

The data sheet and reference manual do not say whether shunt (to ground) capacitors are required on the RTC Crystal.  Can you provide some guidance? 

 

Also, is there a particular type of crystal for this function?

 

Finally, in addition to the RTC, are any other areas (like RAM) maintained by VSTBY when power is removed?

 

Thanks!
