To view and edit the device registers, click the (Registers) icon on the menu to the left. The Registers tab looks similar to the one shown in Figure 3-8.

Figure 3-8 GUI Registers Tab

From this tab, the user can read and write device registers on the EVM. Here are some important notes:

• Use the Selected EVM drop-down menu at the top to choose which device to work with on the Registers tab.
  • Functionally, this button sets the default read and write address in the MCU and then reads all register values back to update the register map. Note that if data is currently collecting at a high frequency, then this can cause a minor delay in the data collection. To prevent this, set the device settings before you starting data collection.
• By default, all changes are automatically written to the device. If desired, then the user can change the Immediate Write setting to Deferred Write to only allow writing when ready.
  • Users can modify writable register values from any of these methods:
    • Through the widget settings in the Field View section on the right.
    • Changing the Value field directly with either hex or decimal values.
    • Double-clicking any individual bit.
• Turning on Auto Read only updates registers in the Registers tab and not the plots in the Results Data section.
  • Leaving Auto Read on while collecting data for plots can interfere with data collection timing.
• For questions about a register or register bit field, click the icon.
  • For even more questions about registers, check the data sheet.
• For convenience, register settings can be saved and loaded back later to any device with the sam register map. To save or reload register settings, go to File > Register Data.

  • Press the Read All Registers button after loading data to update the register map with the actual device values, in case the loaded registers are not compatible with the connected device.
