Output specification
Either complementary output or Pch open drain
output may be selected.
The output circuit configuration is shown in Figure

Select whether input ports (K00–K03) will each be
supplemented with pull down resistors or not. When
"Gate Direct" is selected, see to it that entry floating
state does not occur. Select "With Resistor" for
unused ports.
Moreover, the input port status is changed from high
level (V
DD
) to low (V
SS
) with pull down resistors, a
delay of approximately 1 msec in waveform rise time
will occur depending on the pull down resistor and
entry load time constant. Because of this, when input
reading is to be conducted, ensure the appropriate
wait time with the program.
The configuration of the pull down resistor circuit is
shown in Figure 3.3.1.

Output type
When DC output is selected, R00 becomes a
regular output port. When buzzer output is
selected, by writing "1" to the R00 register, buzzer
drive signal is output from the R00 terminal.
∗
When DC output is selected, the R03 terminal
output type (see Option 8, "R03 specification")
selection is limited to DC output only.
Refer to Figure 3.3.5 for buzzer output waveform.
