Section 16 I²C Bus Interface (IIC)
16.2 Input/Output Pins
Table 16.1 summarizes the input/output pins used by the I²C bus interface.
One of three pins can be specified as SCL and SDA input/output pin of each channel. Two or
more input/output pins should not be specified for one channel.
For the method of setting pins, see section 8.17.2, Port Control Register 1 (PTCNT1).
