Input When this pin’s level is high, the CLKOUT pin is in output mode. When it is low, the CLKOUT pin is “Hi-Z” (High Impedance). This pin is used to output alarm signals, timer signals, timer update signals, Output and other signals. This pin is an open drain pin. This pin is open. This pin is connected to ground. This pin outputs a 32.768kHz signal. Output This is the C-MOS output pin with output control provided via the CLKOE pin. Input This is the serial clock input for I2C BUS communications. This is the serial data input/output for I2C BUS communications. This pin’s signal is used for input and output of address, data, and ACK bits, I/O synchronized with the serial clock used for I2C communication. This pin is an N-ch open drain pin during output. This pin is connected to a positive power supply.
