* The rising edge of the SC line can occur any time between the
rising edge of clock 1A and the falling edge of clock 12A.
** The reference settling window can be extended in the
synchronous mode by adding extra clocks between conversion
cycles. The example shown is the minimum number of clocks
required (12) per conversion cycle.
