This window has inputs organized on the left, and outputs organized on the right. Values for register
variables may be set using multiple techniques. The Functional tab is commonly used to quickly
evaluate the device with nominal settings. The Input Register tab allows the register settings to be
changed, and the Output Register tab allows registers to be viewed. Other tabs provide additional
demonstration and test features for evaluation.
By default the "Functional" tabs have the focus. The values shown in this document will not exactly
match a user's system but the basic window and controls should be identical. This document will
identify the usage and operation of these items in detail.
Always visible along the bottom are the following controls:
•
LED Off – ON/OFF/ON toggle for the green motherboard LED. This LED is a good power-
on indicator but can introduce errors in the optical tests. It is recommended for accurate
measurements to turn the LED off.
•
