Note 1. It requires at least 0.125 μs to stabilize the internal circuit until the A/D conversion operation is started (ADCS
= 1) after the operation of the A/D voltage comparator is enabled (ADCE = 1). If the ADCS bit is set to 1
without waiting for at least 0.125 μs, ignore data of the first conversion.
