Crystal Circuit for MSp430g2553

Hi all,

I am trying to design a custom board for the msp430g2553, i could not find any information on adding an external crystal ( i want to add 16 Mhz or more) to the IC. Can someone point me to any sample circuits , board layout patterns and load capacitor selection . Also what is the maximum frequency of the crystal that i can use with the IC ? Can it be used without load capacitors?

Thanks in advance,

Varun
