The maximum conversion speed, that is, the minimum conversion time this A/D converter can achieve is 2 μs.
However, 4 μs is required before the first conversion result can be retrieved from the conversion result register
(or a maximum of 5 μs is required depending on the conversion start request timing because of the interface
between the system clock and A/D conversion clock). Subsequently, conversion results can be obtained every
2 μs. Therefore, in single conversion mode or highest-priority conversion mode, A/D conversion requires 4 or 5
times the conversion time shown in the above table. In repeated conversion or scan mode, only the first
conversion requires 4 or 5 times the table value (a maximum of 4 to 5 μs) but subsequent conversions are
performed within the time shown in the table (a maximum of 2 μs).
