7.6 Register Map

The ADS101x-Q1 have four registers that are accessible through the I2C interface using the Address Pointer register. The Conversion register contains the result of the last conversion. The Config register is used to change the ADS101x-Q1 operating modes and query the status of the device. The other two registers, Lo_thresh and Hi_thresh, set the threshold values used for the comparator function, and are not available in the ADS1013-Q1.
