3. Output pin states during a reset
Sample Application Circuit
*4. Since this output pin is an open-drain output, a pull-up resistor of between 1 and 10 k
is required. This pin remains high during the reset period even if a
key data read operation is performed.

When the power is first applied, it must be initialized by RES = "L".
The DO pin,being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 and 10 k
) appropriate
for the capacitance of the external wiring so that signal waveforms are not degraded.
Each of The KS4/P4 to KS6/P2 pins must be set to either the key scan output port or the general-purpose output port.
