∗1 VLC1, VLC2, VLC3, VIN and VOUT should not exceed VDD + 0.3V.
∗2 The PE and PF are specified when PA to PD, PX0 to PX2, PY0, PY1 and mask option are port selected.
Note) Usage exceeding absolute maximum ratings may permanently impair the LSI. Normal operation should
better take place under the recommended operating conditions. Exceeding those conditions may
adversely affect the reliability of the LSI.
