correctly, the start bit for conversion can be moved using the
SYNC input pin (pin 2). Asynchronously asserting the
SYNC pin will force the internal clock to swallow a clock
pulse, effectively shifting a bit from the Q
as shown in Figure 10 and Figure 11. For CKSEL LOW, a
single pulse applied asynchronously for two consecutive
