Section 9 I/O Ports
9.2.5
The port 3 pins also function as SCI I/O input pins (TxD0, RxD0, SCK0, TxD1, RxD1, and
SCK1), I
input pins (IRQ4 and IRQ5 * ).
As shown in figure 9.1, when the pins P34, P35, SCK1, SCL0, or SDA0 type open drain output is
used, a bus line is not affected even if the power supply for this LSI fails. Use (a) type open drain
output when using a bus line having a state in which the power is not supplied to this LSI.
Note: * Supported only by the H8S/2268 Group.
The NMOS push-pull outputs of the P34, P35, and SCK1 pins do not reach the voltage of Vcc,
even when the pins are specified so that they are driven high and regardless of the load.
To output the voltage of Vcc, a pull-up resistor must be externally connected.
Notes: 1. When a pull-up resistor is externally connected, signals take longer to rise and fall.
The functions of port 3 pins are shown below.

Pin Functions
When the input signals take a long time to rise and fall, connect an input circuit that
has a noise reduction function, such as a Schmitt trigger circuit.
in table 25.15, DC Characteristics (1). The value of the pull-up resistor should satisfy
the specification in table 25.16, Permissible Output Currents.
