The X1 pin is the input of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz
The X2 pin is the output of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz
No Connection. Can be connected to GND or left floating.
Serial Data (SDA) is a bi-directional pin used to transfer serial data into and out of the device. It has an open drain
output and may be wire OR’ed with other open drain or open collector outputs.
The Serial Clock (SCL) input is used to clock all serial data into and out of the device.
Interrupt Output /Frequency Output is a multi-functional pin that can be used as alarm interrupt or frequency output
pin. The function is set via the configuration register. This pin is open drain and requires an external pull-up resistor. It
has a default output of 32.768kHz at power-up.
