If we are NOT using both SYS_LFXTAL_IN pin and SYS_LFXTAL_OUT pin, which do you recommend below things?

1) SYS_LFXTAL_IN pin = tied GND and SYS_LFXTAL_OUT pin=Open

2) SYS_LFXTAL_IN pin=pull down from 4.7k Ohm to100k Ohm and SYS_LFXTAL_OUT pin=Open

3) SYS_LFXTAL_IN pin =Open and SYS_LFXTAL_OUT pin=Open

Please let me know, thanks!
