Ground of float unused RTC pins?

[robsouthworth]

We aren’t going to use the Real Time Clock module in the MK20DX256VLL7. How do I connect the following pins:

1) VBAT (pin 30)

2) XTAL32 (pin 28)

3) EXTAL32 (pin 29)

Do I ground these pins or leave them unconnected?

You can leave VBAT floating, same goes for XTAL32 and EXTAL32, you can also leave the XTAL pins grounded.
