Note: * 5. These output pins are forcibly set to the segment output function and held low.

* 6. When power is first applied, these output pins are undefined until the S0 and S1 control data bits have been transferred.

* 7. Since this output pin is an open-drain output, a pull-up resistor of between 1 and 10 kΩ is required. This pin remains high during the reset

period even if a key data read operation is performed.
