Other Tab

The ADS7953 requires a clock to operate. The maximum frequency is selected by default for the different

operating modes, providing the maximum 1MSPS throughput rate specified in the datasheet.

The clock setting can be modified in this tab by accepting the default SPI or clock stop mode, a

continuous clock mode with the fastest possible serial clock, or a continuous clock mode with a variable

frequency.

The analog input range can also be specified in this tab as well as the contents of the four MSBs of

channel data (GPIO status or Channel Address of the conversion results).
