Crystal Input. The X1 pin is the input of an inverting amplifier and is intended to be connected to one pin of an external
32.768kHz quartz crystal. X1 can also be driven directly from a 32.768kHz source.
Crystal Output. The X2 pin is the output of an inverting amplifier and is intended to be connected to one pin of an
external 32.768kHz quartz crystal. X2 should be left open when X1 is driven from external source.
Backup Supply. This input provides a backup supply voltage to the device. V
