6.2 Register Map Configuration
This section describes how to use the
Register Map Configuration
tools in the ADS131B26-Q1 EVM GUI. The
GUI provides control over the device register settings via three pages:
1.
Register Map Config
: This page is the main register map configuration space in the GUI, which provides
access to all device registers.
2.
Channel Configurations
: This page displays all register settings from multiple addresses that configure
ADC1A, ADC1B, ADC3A, and ADC3B. The same register settings can also be configured in the main
Register Map Config
page.
3.
Sequencer Configurations
: This page displays all register settings from multiple addresses that configure
ADC2A and ADC2B. The same register settings can also be configured in the main
Register Map Config
page.
6.2.1 Register Map Basics
The register map configuration tool (
) 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
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.
