*1: Conversion time is the value of sampling time (Ts) + compare time (Tc).
The condition of the minimum conversion time is when HCLK=40MHz, the value of sampling time: 300ns,
the value of sampling time: 700ns (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 "FM3
MB9Axxx / MB9Bxxx Series PERIPHERAL MANUAL".
A/D Converter 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)
