To view and edit the device registers, click the (Registers) icon on the menu on the left. The Registers tab will look similar to the one shown in Figure 3-10.

Figure 3-10 GUI Registers Tab

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

• Use the Selected EVM drop-box to choose which device to work with on the Registers page
  • Note, changing this here also changes the same setting for the Configuration tab
  • Functionally, this button sets the default read and write address in the MCU and then reads all register values back to update the Registers page. Note that if data is collected at high frequency, this may cause a minor delay in the data collection. For optimal performance, set the device settings before you start collecting data.
• By default, all changes are automatically written to the device. If desired, you can change the Immediate Write setting to Deferred Write to only allow writing when you are ready.
  • You 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
• Remember that turning on Auto Read will only update registers in the Registers page 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 to any device with the same Registers page. To save or relaod register settings, go to File ➞ Register Data

  • Press the Read All Registers button after loading the data to update the Registers page with the actual device values in case the loaded registers were not compatible with the connected device
