10.1.3 Input/Output Pins
Table 10.2 summarizes the ITU pins. External pin functions should be set with the pin function
controller to match to the ITU setting. See section 15, Pin Function Controller, for details. ITU
pins need to be set using the pin function controller (PFC) after the LSI is set to the ITU mode.
