GND
I²C BUS serial clock input.
Open-drain output corresponds to AD1 to
AD4 input.
Connect this pin a pull-up resister.
The pull-up resister should be above VDD /
4mA (Ω).
Ground terminal.

CLK
Clock input for ADC block.
Input clock is 32.768kHz.
AD converter and voltage hysteresis
comparator use this clock to operate.
