Input
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.
