Notes 1. Connect the REGC pin to VSS via a capacitor (0.47 to 1 µF). This value regulates the absolute maximum rating

of the REGC pin. Do not use this pin with voltage applied to it.

2. Must be 6.5 V or lower.

3. For pins to be used in A/D conversion, the voltage should not exceed the value AVREF(+) + 0.3.

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any

parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge

of suffering physical damage, and therefore the product must be used under conditions that ensure

that the absolute maximum ratings are not exceeded.

Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port pins.
