External Clock Data Read After/During Conversion
It is also possible to begin to read data after conversion and
continue to read the last bits after a new conversion has been
initiated. This method allows the full throughput and the use of
a slower SDCLK frequency. Again, it is recommended to use a

discontinuous SDCLK whenever possible to minimize potential
incorrect bit decisions. For the different modes, the use of a slower
SDCLK such as 20 MHz in warp mode, 15 MHz in normal mode
and 13 MHz in impulse mode can be used.
