The NMOS push-pull outputs of the P34, P35, SCK1 and SCK4 pins do not reach the voltage of
P2Vcc, even when the pins are specified so that they are driven high and regardless of the load.
To output the voltage of P2Vcc, 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.

Pin function
The pin function is switched as shown below according to the combination of the TE bit in
SCR_4 of SCI_4 and the P37DDR bit.
The pin function is switched as shown below according to the combination of the RE bit in
SCR_4 of SCI_4 and the P36DDR bit.
2. For high-speed operation, use an external circuit such as a level shifter.
3. For output characteristics, see the entries for high output voltage for pins P34 and P35

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.
When P37ODR is set to 1, this pin functions as NMOS open drain output.
When P36ODR is set to 1, this pin functions as NMOS open drain output.
in table 24.2, DC Characteristics (1). The value of the pull-up resistor should satisfy
the specification in table 24.3, Permissible Output Currents.
