*1: The conversion time is the value of sampling time (tS) + compare time (tC).
The condition of the minimum conversion time is when the value of sampling time: 150 ns, the value of compare time: 350 ns
(AVCC ≥ 4.5 V). Ensure that it satisfies the value of sampling time (tS) and compare clock cycle (tCCK). For setting of sampling time
and compare clock cycle, see Chapter 1-1: A/D Converter in FM4 Family Peripheral Manual Analog macro part(MN709-00001).
The register setting of the A/D Converter is reflected by the peripheral clock timing. The sampling and compare clock are set at
Base clock (HCLK).
*2: A necessary sampling time changes by external impedance. Ensure that it set the sampling time to satisfy (Equation 1).
*3: The compare time (tC) is the value of (Equation 2).
