■Terminal Functions
Note1: Ｏ: CMOS output terminal, I: CMOS input terminal, Ish: Schmitt CMOS input terminal, A: Analog terminal
Note2: The current value of the ( ) in the I/O (output type) indicates the output drive capability of its terminal.
Note3: The power supply, VDDC can be switched to 3.3V or 5.0V.
Note4: For the terminals without the description of “VDDC is used” in the table, VDD (only 3.3V) is used to drive it.
