Figure 4-11. 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 at the to choose which device to work with on the register map.
– Note, changing this here also changes the same setting for the Configuration tab.
– Functionally, this button sets the default read/write address in the MCU and then reads all register values
back to update the register map. Note that if data is being collected at a high frequency, then this may
cause a minor delay in the data collection. For optimal performance, set 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" directly with either hex or decimal values.
• Double clicking on any individual bit.
• Turning on "Auto Read" will only update registers in the register map, 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, select 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 same register
map. To do this, go to File -> Register Data, as shown in
.
