Serial clock input.
Data input.
Data output.
The CLKOUT pin is a clock output(open drain output)pin with control
output.(Output frequency can be selected as 32.768kHz, 1024Hz,
32Hz, or 1Hz.)
The CLKOE pin is an input pin used to control the output mode of the
CLKOUT output pin.
During the initial power-on(when power is applied from 0 V), if the
CLKOE input pin is at high level(= H), the power-on reset function
selects 32.768kHz as the frequency.
Interrupts output by Alarm and Timer events.(Open drain output)
