Section 17 I²C Bus Interface 3 (IIC3)
17.2 Input/Output Pins
Table 17.1 shows the pin configuration of the I²C bus interface 3. Specifications for the voltage
applied to I/O pins for the I²C bus interface are different from others because of the pin
configuration difference. For details, see section 31, Electrical Characteristics.
