4. Conversion abort command:
An ongoing conversion can be aborted by using the conversion abort command. This is done by forcing
another start of conversion (a valid CONVST_QUAL falling edge) onto an ongoing conversion as shown in
Figure 46. The device enters the wait state after an aborted conversion. If the previous conversion was
successfully aborted, the device output reads 0x3FC00 on SDO.
