The register map configuration tool (Figure 6-2) allows the user to view and modify the registers of the ADS131B26-Q1. This tool can be selected by clicking on Register Map Config under the Pages section of the left window pane. On power-up, the values on this page correspond to the ADC default register settings described in the ADS131B26-Q1 data sheet.

The Register Map Configuration tool has three distinct views that summarize the current register map configuration. At the top of the window is a tabular view where registers are listed in order of ascending hexadecimal address to display the Register Name, Address, Default value, Mode (R = Read-only, R/W = Read/Write), and register Size. To the right, the current register value is also displayed in both hexadecimal and binary formats. The register value can be modified either by entering the desired hexadecimal value in the Value column, or by clicking on the individual bits (read-only bits are listed in gray and cannot be edited).

Below the table is the Field View and Register Description. The Field View on the bottom-left lists the designated bit fields that are grouped together to configure a particular setting. Depending on the bit field, the current setting can be modified either by selecting the corresponding drop-down menu or entering the desired hexadecimal value. The Register Description view on the bottom-right describes the function and settings of the bit fields in the selected register, as described in the ADS131B26-Q1 data sheet.
