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 )
