I guess that it should have something between the "can" and "be" in the title but it is not appearing. Also in the text.
Correct, I am not sure why it is not appearing. This should be /CS. Please see below, this should be the complete details.
When single conversion mode is used, can /CS be taken high after the single conversion is initiated?
The serial interface is independent of the sampling process. So, once the single conversion is initiated, the ADC will power up and perform the single conversion irrespective of the /CS polarity. So, the user can take /CS low, initiate the single conversion and then take /CS high again. When the conversion is complete, /CS can be taken low to read the conversion and another single conversion can be started if required. When /CS is taken high, the DOUT/RDY pin is tristated. Therefore, the DOUT/RDY pin will not indicate the end of the conversion. The user can determine the end of the conversion by reading the status register. Alternatively, the conversion time could be timed out by the microcontroller clock.
