9 Register Map
ADS126xEVM Software
3.4.9
Tab 9: Register Map
Use tab 9 (shown in
) to read and display the current ADS126x register settings. This tab is
useful to see how device settings in the ADCPro software are stored in the ADS126x device registers.
Figure 25. Tab 9: Register Map
Reading back the ADC registers is recommended in all applications to make sure that the ADC settings
are correct and match software assumptions. When the
Register Map
tab is selected or the
Refresh
Register Map
button is clicked; all the device registers are read, the Register Map table is updated, and all
ADC controls (on all tabs) are updated. The
RESET
button reverts all register settings back to the ADCPro
nominal values.
NOTE:
The
RESET
button reverts all ADS126x register settings to a nominal state, as determined
by ADCPro. This nominal state programs the MODE0, MODE1, MODE2, and ADC2CFG
(when applicable) registers to nondefault ADS126x values (indicated by asterisks in the
register map table).
To revert all register settings back to the true ADS126x default values, use the RESET pin
control button on tab 10 (
Extras / About
).
Device settings such as the conversion control and STATUS/CRC byte configurations are
enforced by software to ensure proper communication between hardware and firmware.
The power-on reset (POR) function is also helpful in verifying correct device operation. The
POR
button,
at the bottom of this tab, displays the current value of the POR bit in the POWER register. When clicked,
the
POR
button toggles the value of the POR bit.
Save the register settings to a text file with the
Save to File
button. Recall register settings with the
Load
from File
button. Use this register map text file to document a particular setup. Reference this text file
during development or support on the
E2E™ Precision Data Converter Forum
