Oscillator Circuit Input. Together with X2, 32.768kHz crystal is connected between them.
Oscillator Circuit Output. Together with X1, 32.768kHz crystal is connected between them.
When 32.768kHz external input, X2 must be float.
Serial Clock Input. SCL is used to synchronize data movement on the I
Serial Data Input/Output. SDA is the input/output pin for the 2-wire serial interface. The
SDA pin is open-drain output and requires an external pull-up resistor.
Square Wave/Output Driver. Open drain. Four frequencies selectable: 32.768k, 8.192k,
4.096k, 1Hz when SQWE bit is set to 1.
Power. Primary power for PT7C4307.
+3V Battery Power.
