To allow the user to synchronize the output byte data
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
n
to the Q
n-1
output
as shown in Figure 9 and Figure 10. For CKSEL LOW, a
single pulse applied asynchronously for two consecutive
clock cycles shifts the start bit for conversion from Q
n
to
Q
n-1
. The bit is swallowed following the two clock cycle
pulse width of SYNC on the next triggering edge of
clock (either on the rising or the falling edge of the clock).
Each additional shift requires an additional pulse to be
applied to the SYNC pin. (See Figure 9)
