Can I tell if VBat is good on my K60

I'm using an MK60FN1M0VMD12 and I need my software to check whether the battery for the RTC is good/present. I'm sure there's a register bit somewhere that I can read, but I don't see it in the RTC description. Can someone point me to it?

Thanks in advance, Oliver

Technically, the TIV (Time InValid) flag tells you if VBAT_POR has occured due to Vbat falling below the minimum threshold per the electrical specs.
