*1: Conversion time is the value of sampling time(Ts) + compare time(Tc).
The condition of the minimum conversion time is when HCLK=72MHz, the value of sampling time: 0.222μs,
the value of sampling time: 778ns (AVcc ≥ 4.5V)
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 "12-bit A/D Converter" in "Peripheral
Manual".
ADC register is set at APB bus clock timing. Sampling and compare clock is 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: Compare time (Tc) is the value of (Equation 2)
