CLK Input Serial clock input. DI Input Data input. DO Output Data output. CLKOUT 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. CLKOE Input 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. /INT Output I nterrupts output by Alarm and Timer events.
