11.1.6 Pseudo Code Example

The flow chart in Figure 49 shows a pseudo code sequence with the required steps to set up communication between the device and a microcontroller to take subsequent readings from the ADS1118. As an example, the default Config Register settings are changed to set up the device in FSR = ±0.512 V, continuous conversion mode and 64-SPS data rate.
