• Register Map page for the SPI device variants for read/ write access of register bit fields.
• Driver Control page with configuration and diagnostic options.
• GUI Home page to re-select the EVM if necessary.

5.3.1 Register Map Page (SPI Device Variant)
The Register Map page shown below in
allows the user to read/ write values to individual fields.
Register read-back is read "Every 1 sec" by default. Enabling this will start periodically polling the device
registers. "Off " mode enables a manual read. Auto-read set to "off" is helpful for reducing SPI chatter when
using a logic analyzer or performing EMC measurements.
