VIN, VOUT, VOD and AVREF must not exceed VDD + 0.3V. VFDP and VOD must not exceed VDD - 40V. Specifies output current of general-purpose I/O ports. The large current drive transistor is the N-CH transistor of Port C (PC). Note) Usage exceeding absolute maximum ratings may permanently impair the LSI. Normal operation should be conducted under the recommended operating conditions. Exceeding these conditions may adversely affect the reliability of the LSI.
