4.3.1 Register Map Page (SPI Device Variant)

The Register Map page shown below in Figure 4-4 allows the user to read/ write values to individual fields. Register read-back is read "Every 1 sec" by default. Enabling this starts 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.
