sampling/conversion
All of the sampling, conversion, and data output in the device are started by a trigger. This trigger can be the
RD or CSTART signal depending on the mode of conversion and configuration. The falling edge of the RD signal
and the rising edge of the CSTART signal are extremely important since they are used to start the conversion.
These edges need to stay as close to the falling edges of the external clock, if they are used as SYSCLK. The
minimum setup time with respect to the rising edge of the external SYSCLK should be 5 ns minimum. When
the internal SYSCLK is used, this is not an issue, since these two edges start the internal clock automatically;
therefore, the setup time is always met.
