If access occurs during A/D conversion, values might not fall within the indicated ranges. The use of PORT0 as digital outputs is not allowed when the 12-Bit A/D converter is used. The characteristics apply when AVCC0, AVSS0, VREFH0, VREFL0, and 12-bit A/D converter input voltage are stable. Note 1. The conversion time includes the sampling and comparison times. The number of sampling states is indicated for the test conditions. Note 2. Values in parentheses indicate the sampling time.
