LPC1768 RTC External Components

Hi everyone,

I'm designing a new board for LPC1768 and reading the documentation (and some post) I am not clear which components I must use for RTC (pins 16 and 18) for common use. I must use a crystal or oscillator? and if I use a crystal, it must be of 32.768Khz or 32Khz (according to datasheet)? Also in case to use capacitors, how I can know the correct value?

Thanks for your help
