3. Click the
Registers
icon to open the
Registers
page (also available on the left-side menu). Note that the
"registers" listed are not registers on the TMAG5328 but are internal variables stored in the microcontroller
that are not directly used for EVM evaluation. These variables cannot be modified from the
Registers
page
and can be ignored.

4. At the top of the
Registers
page, change “Auto Read” to “As fast as possible.”
The TMAG5328 also has a
Results
page for viewing the state of the TMAG5328 OUT pin and a
Configuration
page for configuring the DAC. Both of these pages are described in the below sections.

shows an example plot of the OUT waveform. If the TMAG5328 OUT pin is at a high state (LED is
OFF), a "1" is displayed on the graph. If the pin is at a low state (LED is ON), a "0" is displayed on the graph.
The number of samples stored in the plot can be modified by adjusting the "1000" at the top of the screen with
the desired number of samples then clicking enter. In addition, the plot can be exported by clicking the
SAVE
