∗1) VIN and VOUT must not exceed VDD + 0.3V.

∗2) 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.
