11 / 20 page LTC2450-1 11 24501fc Examples of Aborting Cycle using CS For some applications the user may wish to abort the I/O cycle and begin a new conversion. If the LTC2450-1 is in the data output state, a CS rising edge clears the remaining data bits from memory, aborts the output cycle and triggers a new conversion. Figure 9 shows an example of aborting an I/O with idle-high (CPOL = 1) and Figure 10 shows an example of aborting an I/O with idle-low (CPOL = 0). A new conversion cycle can be triggered using the CS signal without having to generate any serial clock pulses as shown in Figure 11. If SCK is maintained at a LOW logic level, after the end of a conversion cycle, a new conversion operation can be triggered by pulling CS low and then high. When CS is pulled low (CS = LOW), SDO will output the most significant bit (D15) of the result of the just completed conversion. While a low logic level is maintained at SCK pin and CS is subsequently pulled high (CS = HIGH) the remaining 15 bits of the result (D14:D0) are discarded and a new conversion cycle starts. Following the aborted I/O, additional clock pulses in the CONVERT state are acceptable, but excessive signal tran- sitions on SCK can potentially create noise on the ADC during the conversion, and thus may negatively influence the conversion accuracy.
