Section 9 I/O Ports
9.3.4
P3ODR controls on/off state of the PMOS for port 3 pins.
9.3.5
The port 3 pins also function as SCI I/O pins, I2C bus interface 2 I/O pins, and interrupt input
pins.
As shown in figure 9.1, when the pin P34, P35, SCK1, SCK4, 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.

Description
When each of P37ODR, P36ODR, and P33ODR to
P30ODR bits is set to 1, the corresponding pins P37,
P36, and P33 to P30 function as NMOS open drain
outputs. When cleared to 0, the corresponding pins
function as CMOS outputs.
When each of P35ODR and P34ODR bits is set to 1,
the corresponding pins P35 and P34 function as
NMOS open drain outputs. When cleared to 0, the
corresponding pins function as NMOS push pull
outputs.
