The High Precision Mode increases the accuracy of the data measurement to 16-bit accuracy. This is useful for applications where the level of precision required to accurately measure the sensor output needs to be higher than 12-bits. When High Precision Mode is selected from the Operating Modes drop-down menu and the SET button is pressed, the device starts conversions and starts accumulating the conversion results in an accumulator. The device stops accumulating the conversion results in the accumulator after 16 conversions. If the user aborts the sequence before 16 conversions, then the device will abort the sequence. To understand the steps required to configure the device in this mode, refer to the ADS7142-Q1 data sheet.

Figure 4-6 highlights the ADS7142-Q1 GUI working in High Precision Mode. The maximum number of accumulator count that can be entered into the ACCUMULATOR_CFG register is 15 (0x0F) which corresponds to 16 conversions.
