*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: 0.3μs,
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*4 of sampling time and compare clock cycle, see chapter "Chapter:12-bit A/D Converter" in
"FM3 FAMILY MB9Axxx/MB9Bxxx Series PERIPHERAL MANUAL".
*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).
*4: The register setting of the A/D Converter is reflected by the timing of the APB bus clock.
Sampling clock and compare clock are set with the base clock (HCLK).
About the APB bus number which A/D Converter is connected to, see chapter " BLOCK DIAGRAM"
in this data sheet.
