In the schematic and layout pdf files shouldn't pins 33 and 34 be connected to ground?

Michael

nrf51x22_qfab_schematic.jpg I was going over the schematic and layout pdf files for the nrf51x22 before I began to create my own board and noticed that Pins 33 and 34 are not connected to anything. Aren't both pins supposed to be connected to ground? or is this connection unnecessary? I'm planning on connecting both to ground because the datasheet says to and doesn't say NC, but I thought I'd ask to at least point this out.

    link text I think this is the link. You can also get there via p. 77 of nRF51822 PS v.3.1. Also, if anyone who reads this cares to answer, are there specific oscillators for X1 and X2 that are tried and true for the nRF51822? I see the recommended capacitance and tolerance for both, but I'd like to minimize all potential issues for an initial prototype.

    Edit: Am I missing something here? Because the same pins are NC on the pcb for the nRF51 DK.
